Pete Wentz Just Too Smart For Ashlee Simpson

Intellectually mismatched? We know she’s got the vocal prowess of a broken toaster and a wet noodle, but is Ashlee Simpson really just “too stupid to keep up” with her soon-to-be ex-husband Pete Wentz? That’s the interesting explanation one Fall Out Boy mole is offering for the shocking bust-up of Pete and Ashlee’s 2 1/2 year marriage.

The Gossip Wire went into overdrive Wednesday following the announcement that Simpson had filed for divorce from the rock bassist, citing the ever-popular “irreconcilable differences.” The couple married in May 2008 and have a (bizarrely named) son, Bronx Mowgli, together.

It didn’t take long for speculation to begin about the reason behind the split.

“They also are on different planes,” a source-type with ties to the couple told The Chicago Sun-Times this week. “To be blunt, Pete is a helluva lot smarter than Ashlee. … After a while I think she realized she just couldn’t keep up with him in a lot of areas.”

Burn!

Ashlee’s seeking primary physical custody of the two-year-old, with shared legal custody. She’s also asking for spousal and child support. Apparently, the couple had no prenup (which kinda proves the whole “Ashlee Is An Idiot” argument…)
