Reality TV stars Holly and Heidi Montag's father has been arrested for the alleged sexual abuse of a 13-year-old girl.
Bill Montag allegedly committed acts of sexual abuse at least 50 times until the girl turned 17, according to TMZ.com.
The unidentified girl claims she was given "back rubs in her bedroom" by the accused, who allegedly performed a sex act on her when she was just 16.
Sources close to Heidi Montag tell the website the accuser is "determined to destroy the family" and the former The Hills star is convinced her dad will be exonerated.
Bill Montag appeared on TV when he walked Heidi down the aisle before she exchanged vows with Spencer Pratt in 2009.
