Kat Von D's publicist is denying online reports claiming the Mexican-born reality television personality is pregnant with her beau Jesse James' baby. "They've only been dating for a few weeks. She is not pregnant. That's absolutely absurd," her representative told People.com. James, a celebrity motorcycle customizer who has also appeared on several reality shows, was recently divorced from actress Sandra Bullock after almost five years of marriage. Bullock has since adopted a baby boy named Louis.
