10 Celebrity love triangles you NEVER knew about (With Pictures)

4. Michelle Trachtenberg – Ashlee Simpson – Pete Wentz

You all remember Michelle Trachtenberg, Disney’s Ice Princess and the it-girl from like 2005? Well it turns out her love life wasn’t as Disney as her acting career; she was embroiled in a nasty love triangle with Fallout Boy hottie Pete Wentz and “La La” singer Ashlee Simpson. After breaking up with Trachtenberg, Wentz became involved with Simpson. They dated for a few years, but tensions didn’t dissipate between the two ladies. At a party in 2009, Ashlee Simpson picked a fight with Trachtenberg, screaming: “I hope you know, the whole time you were dating Pete, I was f****** him!” Guess she was lying in her song when she said: “Hey now, don’t put words up in my mouth, I didn’t steal your boyfriend.”
