Sexy Victoria Beckham is going after critics who have accused her of only forging a close relationship with Katie Holmes and Tom Cruise to further her acting career.The former Spice Girl has become close friends with the Cruise family when she and her husband David moved to Los Angeles California last July. Since the Hollywood move, the Spice Girl has made a transition to the small screen, making a number of guest appearances, most notably on hit television comedy Ugly Betty. But Beckham insists she is not interested in a Hollywood acting career because she is well aware of her lack of skills in front of the camera, and has snubbed several film roles as a result.She says, "I’m happy doing what I’m doing right now. I’m a terrible actress.Everyone thinks I’m only friends with Tom and Katie to be in a movie but it’s not true. I’ve turned down lots of roles."
