Serena Williams was snapped having a selfie with "boyfriend" Patrick Mouratoglou as the tennis champ and her coach arrived in Perth, Australia for the Hopman Cup on Saturday.

Photos of the pair were published on Daily Mail and it seems Serena Williams have no nerves as she prepares for the tournament, which will be used in preparation for the Australian Open.

"But as World No.1 Serene Williams landed at Perth airport on Saturday, all that appeared to occupy her mind was the angle that showed off her best side as she posed for snaps with beau Patrick Mouratoglou," it said.

"The 5ft 9ins star looked in perky spirits as she beamed for the phone camera wearing thick-rimmed glasses and clad in dark sports clothes and trainers," the tabloid added.

Serena Williams and rumored boyfriend Patrick Mouratoglou, who is also her coach, had a roller-coaster 2014 with her inconsistent play, largely due to injuries.

In an earlier interview with the New York Times, the coach said: "The only explanation we have is that after the year and a half she spent winning so much and playing so much, she had a moment where she dropped a bit in terms of her nerves and her mental game and then lost matches. In the losing matches, she lost a bit of confidence."

But Serena Williams in a Twitter Q&A denied that she's dating her coach or anybody, according to Tennis-X website.

She tweeted: "To answer all your questions I'm single and I have been single so the speculations can stop."

That's contrary to what Maria Sharapova said in an earlier dialogue with the press when the multiple grand slam winner described her as boring. "Maybe she should talk about her relationship and her boyfriend that was married and is getting a divorce and has kids," Sharapova said.
