Newly single singer Pete Wentz has been spotted with a mystery brunette in Los Angeles-sparking rumours he's moved on after his split from Ashlee Simpson.

The rocker and Simpson announced in February that they are seeking a divorce, citing irreconcilable  differences.

Now, the bassist has sent gossips into a spin after he was photographed out and about in West Hollywood with a young brunette, reports the Daily Star.

Wentz and Simpson tied the knot in May 2008, and have a two-year-old son.
