The 21-year-old Russian was wearing a LeBron James jersey for the game while Aussie ace Kyrgios preferred to don a Boston Celtics uniform.

“Who is your favorite team?” Kalinskaya captioned the picture, further spurring rumors that she might be dating Kyrgios – who is a big basketball fan.

Earlier this month the Australian player was spotted planting a kiss on Kalinskaya’s forehead in Acapulco, after he withdrew from his first-round match at Mexico Open.

The pair were caught eating tacos together with Kyrgios kissing his rumored Russian match-mate.

Neither player has ever talked about their romantic relationship, but the recent picture shared by Kalinskaya was seen by many as unofficial confirmation of their coupledom.
