Looks like the honeymoon may be over for Ashlee Simpson and Pete Wentz. The couple, who were married less than a year ago in May 2008, are reportedly facing some problems, according to Page Six.

“Ashlee and Pete are on the rocks,” a source says. “He is going out all the time and she’s stuck at home. It’s just not working.” A rep for the couple denies the story, saying, “This is not true. Everything is fine in their world.” The couple’s first child, Bronx Mowgli, was born in November.
