Eight facts about Costeen Hatzi, one pattern: most of her public profile is still tied to her ex, but she’s actively creating distance.

Are Nick Kyrgios and Costeen Hatzi Still Together?

No, they are not. The pair split after nearly four years together, with the first public signs appearing in late March 2025 when both removed each other’s initials from their Instagram bios (People (celebrity news)). Reports confirmed the breakup, and by June 2025, Kyrgios broke his silence during an Instagram Q&A (People).

Why did they break up?

• Lifestyle differences were cited by sources close to the couple (Greek City Times (Greek-Australian news)).
• Neither party has given a detailed on-the-record explanation.

Did Kyrgios confirm the split?

• Yes. In a June 11, 2025 Instagram Q&A, he said “Things happen” and “I wish her nothing but the best” (People).
• He added that “So many incredible memories” would stay with him.

The implication: the breakup appears to have been mutual and handled privately, with both sides choosing to move forward without drama.

What Does Costeen Hatzi Do for a Living?

Hatzi is a social media influencer and businesswoman based in Australia. She is represented by The Ministry of Talent, a talent agency that manages influencers and content creators (New York Post (U.S. sports and news)). Her Instagram feed—with roughly 171,000 followers—features brand partnerships, lifestyle content, and travel posts.

How does Costeen Hatzi make money?

• Sponsored posts and brand collaborations on Instagram.
• Potential affiliate marketing and paid appearances.
• Her agency handles commercial deals.

Is Costeen Hatzi an influencer?

• Yes, she fits the definition of a micro-influencer with a curated lifestyle brand.
• She has not disclosed exact earnings, but influencer income at her follower level typically ranges from a few hundred to a few thousand dollars per post.

What this means: Hatzi’s career is legitimate and agency-backed, but it’s still early-stage. The breakup may actually widen her reach if she successfully pivots to solo content.

What Is Costeen Hatzi Doing Now?

Since the split, Hatzi has been focusing on her own career and spending time with friends and family. In April 2025, she told reporters that life had been “good” and “wonderful” after the relationship ended (New York Post). She has not publicly discussed dating anyone new seriously.

Did Costeen Hatzi move on from Kyrgios?

• She has stated she harbors no regrets and wishes him well (Greek City Times).
• She said “We haven’t spoken” when asked about current contact.

What does her Instagram reveal?

• Her feed continues to show solo and friend-focused content.
• She has removed most couple-related posts and is building a fresh personal brand.

The pattern: Hatzi is carefully controlling her public image—acknowledging the past while signaling a forward-looking, independent identity.

Is Nick Kyrgios Engaged to Costeen Hatzi?

No. There is no evidence of an engagement. Rumors occasionally surfaced during their relationship, but no official announcement was ever made (Greek City Times).

Were there engagement rumors?

• Some social media speculation, but no credible reporting.

Did Nick propose?

• No public proposal or ring was ever reported.

The trade-off: the absence of an engagement ring means the split was a clean break—no legal entanglements, no public promise to undo.

Why Is Nick Kyrgios on OnlyFans?

Kyrgios launched an OnlyFans page in 2024, using the platform to share exclusive content and interact with fans (New York Post). The move is part of his post-tennis career strategy, capitalizing on his outspoken personality to generate income outside of tournaments.

Did Kyrgios start an OnlyFans account?

• Yes, it is active and promoted on his social media.

What does he post?

• Behind-the-scenes content, personal updates, and direct fan interactions.
• He has described it as a way to “connect with fans on a deeper level.”

What this means: Kyrgios is diversifying his income streams early, and his OnlyFans launch—while unrelated to the breakup—shows a shift in priorities that may have affected the couple’s dynamic.

How Old Is Costeen Hatzi and What Degree Does She Have?

Hatzi is 25 years old, born in 1999 or 2000. She holds a university degree, though the specific field and institution have not been publicly confirmed (People (celebrity news)).

Costeen Hatzi age

• 25 years old (born 1999–2000).

Costeen Hatzi education background

• She has a university degree, but no verified details on the subject or university.

The catch: the lack of publicly available education details is unusual for an influencer of her profile, suggesting either a deliberate privacy choice or a gap in media reporting.

What Is Costeen Hatzi’s Net Worth and Height?

Neither figure is independently substantiated. Her net worth is estimated to be modest—likely in the range of a typical micro-influencer—but no reliable source has verified a number. Similarly, her height is not confirmed, though she appears tall in photos (New York Post).

Costeen Hatzi net worth

• Not publicly verified; estimates range from $100K–$500K AUD based on influencer averages.

Costeen Hatzi height

• Not confirmed; visual estimates suggest approximately 5’6″–5’8″.

Why this matters: the opacity around her personal metrics is itself a data point—Hatzi is not feeding the celebrity gossip machine with easy biographical details.

Timeline of Key Events

• 2021: Costeen Hatzi and Nick Kyrgios begin dating (People).
• Early 2025: Rumors of relationship troubles circulate.
• March 2025: Initials removed from Instagram bios; split first reported (Greek City Times).
• April 2025: Hatzi gives her first post-split interview, saying she has no regrets (New York Post).
• June 11, 2025: Kyrgios breaks his silence on Instagram (People).
• August 2025: Split confirmed by multiple sources; Hatzi speaks again about moving forward.

The pattern: the timeline shows a gradual public unraveling, with both parties eventually speaking on their own terms.

Confirmed Facts vs. What’s Unclear

The takeaway: the knowns are solid, but many personal details remain undisclosed, likely by design.

What They Said

“I have no regrets. I was a fully supportive girlfriend.”

— Costeen Hatzi, speaking to New York Post

“Things happen… I wish her nothing but the best. So many incredible memories.”

— Nick Kyrgios, via Instagram Q&A, reported by People

“I hope he finds peace and happiness within himself.”

— Costeen Hatzi, speaking to Greek City Times

Both have spoken with dignity, but the asymmetry is notable: Hatzi has given more detailed interviews, while Kyrgios kept his response to a single social media interaction.

For Costeen Hatzi, the road ahead is about converting public sympathy into a sustainable career. For the Australian influencer market, the lesson is clear: build a brand independent of your partner, or risk being defined by a breakup. Her next six months will determine whether she can turn that risk into a reinvention.

Following her separation from Nick Kyrgios, Costeen Hatzi has focused on her career pivot after the split, marking a significant shift from her previous public profile.
