Jackass star Bam Margera is convinced his upcoming televised marriage will not end in tears, despite the after-effects reality TV shows NEWLYWEDS: NICK AND JESSICA and MEET THE BARKERS had on their respective couples. Margera will wed fiancee MISSY ROTHSTEIN on MTV programme BAM'S UNHOLY UNION, the first episode of which airs tonight (30JAN07). However, the stuntman believes the fact Rothstein is not a celebrity bodes well. He tells the New York Daily News, "When a celebrity and another celebrity try to make it work, it usually winds up in a divorce because they're too busy doing their own thing. "Not to mention their 'thing' consists of frenching other people in movies. I don't care if you're an actor, people get jealous. "Missy's just a girl from Pennsylvania who has no desire to be an actor." Newlyweds stars Nick Lachey and Jessica Simpson finalised their divorce in June 2006, while Meet The Barkers' Travis Barker split from wife SHANNA MOAKLER in August 2006.
