Nick Kyrgios is through to the Wimbledon semi-final for the first time in his career, but the controversial Australian tennis star is remaining tight lipped about his off-court battle

Ahead of the stellar match, Australian police confirmed the 27-year-old will be required to appear in a Canberra court next month amid allegations of assault by a former girlfriend.

Kyrgios says it’s been difficult to read reports about the alleged claims, but it did not impact him mentally.

During a post-match press conference, Kyrgios told reporters he has a lot on his mind at the moment, but he’s been advised by his lawyers to stay quiet.

The Aussie put on an incredible show for fans around the world, powering through to the next round in a straight sets victory over Christian Garin.

When it comes to reaching the semi-final, Kyrgios says he’s just so proud of his recent achievements.

The Association of Tennis Professionals is aware of the Australian case involving Kyrgios but declined to comment further at this time.

Spectators filled the All England Club on Monday to watch the biggest tennis stars hit the court at Wimbledon.

After coming back from a lengthy break, Serena Williams lost in three sets to 24-year-old, Harmony Tan.

“When I saw the draw, I was really scared. I don’t know what to say, I’m so emotional now because she’s a superstar,” Tan says.

Tan took the first set 7-5, before Williams took over 6-1. Tan fought back to win a thrilling third set tie-breaker.

Despite her dramatic loss, the former world number one is brushing off retirement rumours.

Kyrgios spits at crowd

Meanwhile, in men’s singles, Aussie tennis star, Nick Kyrgios, caused a bit of a stir calling the chair umpire a “snitch” after she supposedly complained to the court umpire about his behaviour.

The 27-year-old will likely be up for a fine for also spitting towards a fan during the match.

Kyrgios says there was a lot of disrespect from the crowd, which is why he admitted to spitting towards a fan.

“I’ve been dealing with hate and negativity for a long time, so I don’t feel like I owed that person anything,” he says.
