Once married to Ashlee Simpson, Fall Out Boy rocker Pete Wentz is in a good position to share his thoughts on former sister-in-law Jessica and the family Simpson. Turns out, Jess is no dummy.
Pete spilled the beans on an episode of US talk show Watch What Happens Live, where he sang his praises for Jess as well as ex-wife Ashlee, and their father, Joe Simpson.
On Jess, Pete points out it's no accident she's a massively successful businesswoman.
"She’s got a multi-billion-dollar company. I think she’s a secret genius," he said, referring to her clothing line, TV show Fashion Star, her Weight Watchers deal and many other endorsements.
Pete also described Ashlee as a "great mother" to their son Bronx, and Joe Simpson, despite his recent bad press, as a "great grandfather and a really good guy".
Rock star Pete shares custody of Bronx with Ashlee, so he remains close to the Simpson house.
Whether Jess is a genius or not is still up in the air, but with the kind of money her billion-dollar empire makes, she can certainly afford a university degree or two.
