Twilight star Kellan Lutz was recently asked to play Britney Spear's love interest in the music video for her latest single "I Wanna Go," but the beefy actor turned down the role, according to HollywoodLife.

Britney and Kellan first met two weeks ago when he attended her fund-raising event for the St. Bernard Project in Los Angeles. But Kellan wasn't the singer's only pick for leading man ... Britney also approached Matthew McConaughey to portray her love interest.

The "Till The World Ends" singer has her music video boy toy rescuing her from the crowd of pesky paparazzi before making out with her in the back seat of a car.

Sounds reminiscent of Stephen Dorff's role in "Everytime," circa 2004. Maybe if McConaughey turns down the role too, Dorff could reprise his character!
