Ashlee Simpson And Pete Wentz: Details Behind The Divorce

Insiders say the couple have 'just grown apart.'

Ashlee Simpson and Pete Wentz’s split may seem shocking to fans, but insiders close to the pair say there’s little drama behind the scenes.

According to People, sources close to Simpson and Wentz have said the pop star and Fall Out Boy rocker aren’t mixing any emotional theatrics into their impending divorce. One person connected to the situation said the pair are riding out the breakup peacefully.

“It’s very amicable. They’re on very friendly terms and speaking — it’s fine,” an insider said. “They’ve just grown apart. They’ve been growing apart for quite some time.”

The source added that parenting their toddler remains their top priority. “It’s all about [their 2-year-old son] Bronx for them. They’re fantastic parents — Pete says she’s a great mom, and she says he’s a great father,” the insider said. “It’s about Bronx’s care and well-being and happiness for them.”

Insiders have also echoed the “growing apart” reasoning to TMZ, adding that their respective careers — Simpson has largely eschewed the spotlight since 2008′s Bittersweet World, while Wentz has dabbled in fashion and piloted other musical projects — wedged them apart.

“After Bronx was born, Ashlee made a conscious decision to get out of the business, but Pete’s heart was in music so he kept touring and that became a big issue in their relationship.”

While insiders have maintained the split is drama-free, TMZ reports that Simpson left due to Wentz’s antics. “It’s really all about Pete’s erratic behavior,” the source said. “She really wanted out.”

Publicly, the couple have been big on e-affection, gushing about each other on Twitter as recently as two days ago. “Dont forget 2 notice-when i look into the lil dudes eyes & smile, the way he loves. i realize @ashsimpsonwentz is a good moma + so much more,” Wentz tweeted Monday.

Just last month Simpson doled out a sweet missive to her husband. “@petewentz I already miss your handsome face!” she wrote on January 19.
