Fall Out Boy and Craig Owens (badXchannels, D.R.U.G.S., Chiodos) both appear on a new song from avant-pop duo 100 gecs, a remix of the twosome's "hand crushed by a mallet." It's undoubtedly a bop, but the pairing's all the more impressive considering Owens' past with Fall Out Boy's Pete Wentz.

Does anybody remember what transpired between the two emo-rock titans back in 2011? As Wentz was winding up his short-lived marriage to Ashlee Simpson — the sister of entertainer Jessica Simpson and a prospective pop star herself — reports posited that Owens was shacking up with Ashlee.

At the time, certain gossip rags presented the love triangle as a double-cross since Owen's D.R.U.G.S. (Destroy Rebuild Until God Shows) had just released their debut studio album under the banner of Wentz's label, the former Fueled by Ramen imprint Decaydance Records (now know as DCD2).

As Perez Hilton told it at the time, "Ashlee Simpson has moved on from her not-so-officially ended marriage and is dating Craig Owens, a friend and recording artist under Pete Wentz's record label. Sources close to Pete say that the news of his friend dating his estranged wife has left him 'shocked.'"

Is it now water under the bridge? When 100 gecs — the enigmatic experimental act that's received much hype from the indie press — dropped their remix album 1000 gecs and the Tree of Clues on Friday, the effort contained the new song featuring Fall Out Boy and Owens along with vocalist Nicole Dollanganger.

Listen to it below.

The finalization of Wentz and Ashlee's divorce came in late 2011. Since then, the Fall Out Boy bassist has been with his current partner, Meagan Camper, with whom he has two children. (He also has a kid with Ashlee.) Ashlee married actor Evan Ross in 2014.
