Kellan Lutz Goes to the Gym, Makes Fans Sweat

Kellan Lutz was spotted leaving the gym yesterday in North Hollywood. The Twilight star seems to be going to the gym a lot to keep his great physique — and we're definitely not complaining! Maybe he feels the pressure to maintain an amazing beach bod to keep up with girlfriend AnnaLynne McCord, who is known to have one the hottest bodies in Hollywood!

The pair has been getting pretty serious lately, they haven't even tried to conceal their relationship! Since being so out there with their romance, neither of them have seemed happier!

Kellan doesn't just look good, he does good too! Last week, at VH1's Do Something! Awards, he won the Do Something! for Animals award, for his work helping PETA.
