Ashlee filed for divorce just one month ago and she's reportedly already dating D.R.U.G.S musician Craig Owens. And to say Pete is pissed is an understatement.
Ashlee was spotted shopping in LA with Craig with his arm around her shoulders. You know what that means. They're banging.
A source told Us Weekly: "Pete did a lot for this guy. Craig was in another band and got kicked out. Pete found Craig, built a band around him and signed him. He's shocked at how this guy is repaying him."
Hope this new guy is into drama, because Ashlee and Pete are engulfed in a child custody battle as we speak.
Stay tuned for more deets on Ashlee's new man!
