Just weeks after Ashlee Simpson was spied canoodling with her new actor beau Vincent Piazza - her former hubby Pete Wentz appears to have moved on too!

Or should we say moved backwards…

The Fall Out Boy star is rumoured to have rekindled the flame with his ex, Michelle Trachtenberg!

According to People Magazine, the former couple - who dated before the singer got with Ash - were snapped on a cosy coffee date in Los Angeles this weekend.

And even if the relationship isn’t back on – we’re sure his baby momma won’t be too pleased to hear the pair have been hanging out again…

Back in 2009 the songstress reportedly got into a right old cat fight with the ‘Gossip Girl’ stunner at a showbiz party at LA’s Wiltern Theater.

At the time a source told Perez Hilton,

"[Ashlee] was staring directly at Michelle and started hurling insults at her.”

The rock chic then allegedly told the actress, "I hope you know, the whole time you were dating Pete, I was f---ing him!"

Meow!

Meanwhile, Michelle’s GG co-star Taylor Momsen has apparently found love with edgy rocker Natt Weller!



According to The Sun newspaper, the son of ‘Broken Stones’ star Paul Weller was reportedly spotted backstage with the heavily made-up wildchild at London’s Wireless Festival.

The 23-year-old also gushed about the Pretty Reckless singer’s performance at the bash on Twitter, saying,

"Watching @taylormomsen wireless she's killing it her vocal is bang on!! (sic)"
