Cameron Diaz displays bulging biceps

Cameron Diaz has been taking her fitness regime a bit too seriously.

London: Cameron Diaz has always been a fitness enthusiast but it seems that the actress, who showed off a muscular look, is taking her fitness regime too seriously.

The 38-year-old actress, who is dating baseball player A-Rod, seemed to have packed in some muscles as she picked up an award at the annual CinemaCon convention in Las Vegas recently, reported a website. Diaz, who accepted the prize for `Female Star Of The Year` from Drew Barrymore, was wearing a strappy, fitted white dress for the occasion, which showed off her recently acquired biceps. The muscular look appears to be popular with her current beau and the couple are often seen hitting the gym together. A-Rod`s ex-wife Cynthia also had well-toned biceps - while it is a look also favoured by another one of his exes, Madonna. PTI
