Ashlee Simpson has brushed off reports her marriage to rocker Pete Wentz is in trouble, insisting "everything is fine".

The couple wed in May last year and welcomed baby boy Bronx in November .

Rumors surfaced earlier this month suggesting Simpson was unhappy with the Fall Out Boy star's constant partying, while she was left at home to look after their son.

A source says, "Ashlee and Pete are on the rocks. He is going out all the time and she's stuck at home. It's just not working."

But Simpson's representative has denied the allegations, assuring fans the couple is still happily married and Wentz will return to their Los Angeles home once he completes his band's Australian tour.

The spokesperson tells the New York Post's Page Six, "This is not true. Everything is fine in their world."
