Retired from competitive tennis years ago, the Russian born beauty recently posed in a white bikini on the cover of Maxim magazine, where the 29-year-old is seen playfully nibbling on a dog tag.
In an interview with the magazine, Anna coyly refused to give a straight answer when asked if she was single.
"Single as in on paper? Yes, but I'm in a relationship,” news.com.au quoted her as saying.
Anna also spoke about her work with the USO (United Services Organisations), an organisation that supports US troops who are posted overseas.
"I love it. I have the best fans and it was really cool to see that they'd have pictures from my tennis days up on their walls.
"And I don't think I've ever met nicer or more respectful people than in the military,” she added.
