Former world No. 7 Nicole Vaidisova is working on her fitness, but has yet to decide whether she will launch a comeback, TENNIS.com has learned.

A former semifinalist at Australian Open and Roland Garros, Vaidisova retired from tennis in 2010 at age 20, saying she had lost her desire to compete. The 24-year-old says that once she gets fit enough she will "see" whether she wants to try and make a comeback.

Vaidisova married fellow Czech player Radek Stepanek in 2010, but the two are currently in divorce proceedings. Stepanek is currently dating another Czech player, former Wimbledon champion Petra Kvitova. Vaidisova’s camp denied a report on Czech website that claims she is currently dating Kvitova’s ex-boyfriend, Adam Pavlasek.
