This year’s U.S. Open served up a curious match.

On Monday, Croatian-Australian tennis star Ajla Tomljanović was spotted in the box of Italy’s Matteo Berrettini, who defeated Russia’s Andrey Rublev in the fourth round, according to Tennis Tonic.

An Instagram post also surfaced of Tomljanović, 26, who previously dated Australian bad boy Nick Kyrgios, at Italian eatery Via Della Pace in New York with Berrettini, 23, and Canada’s Félix Auger-Aliassime.

“Wow wow wow… can someone play tennis here?! 😱😍😜 Grazie infinite @ajlatom @matberrettini@felixaliassime,” restaurant co-owner Giovanni Bartocci shared with his followers.

Though Tomljanović and Berrettini’s current status remains unclear, her previous relationship with Kyrgios, 24, was long-documented.

In 2017, Tomljanović scrubbed all photos of the couple from her social media page after Kyrgios was spotted with other women during Wimbledon. They started dating in 2015.

As for Kyrgios’ recent affairs, he was photographed in August with Genie Bouchard’s twin sister, Beatrice.

Both Kyrgios and Tomljanović’s Open runs have come to an end this year. Berrettini faces Rafael Nadal in the semifinals on Friday.
