Former Miss USA Shanna Moakler has denied every being unfaithful to her husband, rocker Travis Barker, and claims to be a good mother to her children.

People magazine said that during a recent interview, the former Playboy Playmate said her husband's allegation last month that he was filing for divorce due to her infidelity and child neglect was untrue.

The 30-year-old model said she is very active in the lives of her three children -- including one from a prior relationship with boxer Oscar De La Hoya -- and has no problem sharing the children with her husband despite his comments.

Moakler said that after having their 2004 marriage covered on the MTV reality series "Meet the Barkers" last year, she and Barker began to have problems six months ago.

"I think what happened was that he was surrounded by a lot of really bad people," she told People. "When you have a lot of people kissing your butt all day, and then you come home to the big negative all the time, after a while it takes its toll."
