MELBOURNE: Despite being the highest paid sportswoman on the planet and one of tennis’ most recognizable faces, Maria Sharapova insists she is shy and doesn’t need expensive things to make her happy.

But the massively wealthy world number two, who has topped the Forbes list of richest women athletes for 10 years, also confesses to loving art and architecture. She also enjoys karaoke, belting out Cher hits.

“I’m quite shy, actually, in the beginning,” the US-based Russian told The Age newspaper in Melbourne as she prepares to launch her Australian Open campaign.

“I’m quite an easy person. I don’t need a lot of big or expensive things to make me happy.”

Despite having homes in Florida and California, where the paparazzi thrive, and being the face of everything from German cars to French mineral water, the 27-year-old said she is able to live a relatively obscure life.

For this, she is grateful.

“No matter what people define me as, and say that I am quite well-known, I’m able to live a very normal, easy life,” said Sharapova, whose partner is world number 11 Grigor Dimitrov.

“I’m lucky enough not to have a lot of cameras following me around.

“At the end of the day I can wake up and not feel like I have to put on red lipstick. I don’t know if I’d ever be able to manage that!

Her Manhattan Beach home is a private gallery, Fairfax said, with the Russian nominating her Californian friend Chris Gwaltney and edgy Briton Tracey Emin as her favorite artists.

“I love architecture and modern art, so I actually enjoy building projects and looking at beautiful pieces and adding them to my collection,” she said.

“I have a lot of beautiful white walls and concrete walls, and I love different textures and, I don’t know, I like looking at something that just puts a smile on your face, makes you happy.

“I really love art. Every time I go to a city I always try to find my way to the cool galleries.”
