Ashlee Simpson & Pete Wentz Hold Hands

Ashlee Simpson and Fall Out Boy’s frontman boyfriend Pete Wentz hold hands while out partying together at Hollywood’s latest hot spot Parc on Saturday night.

The on-again-off-again rocker couple were spotted kissing and cuddling inside Parc, where they celebrated a friend’s birthday.

“They definitely weren’t hiding the fact that they were together,” one spywitness said. “They were making out a lot and they were pretty intense.”

Ashlee, 22, and Pete, 27, have been together since September 2006.

It’s been rumored earlier this week that Ashlee has found an unlikely music legend to help her record her new album – The Cure rocker Robert Smith. Smith will reportedly sing alongside Ashlee on a track to follow-up her 2005 album I Am Me.

Fall Out Boy announced on Friday that they have to delay their national tour because of “personal issues.”
