Fall Out Boy star Pete Wentz has given his blessing for pop singer Robbie Williams to date his former girlfriend.

Bassist Wentz split from 21-year-old actress Michelle Trachtenberg last year and press reports have subsequently linked Trachtenberg to the She's The One star.

Although Wentz remains close to his beautiful ex, he's philosophical about her love life and agrees Williams would be a great match.

He says, "I talked to her last night actually. We didn't talk about Robbie Williams, though. I do think it's definitely a possibility.

"I've seen Robbie making his rounds in California. He's a good looking gentleman. So I wouldn't see why anybody wouldn't."
