We should have seen this coming when 2 Chainz posted a photo on Instagram with Pete Wentz last month: 

But the artist formerly known as Tity Boi has quite the feature in Fall Out Boy's latest video, "My Songs Know What You Did in the Dark (Light Em Up)," where 2 Chainz, well, lights everything on fire.

Fall Out Boy is back after a three-year break. The band announced this morning, via a press release, that their new single "My Songs Know What You Did in the Dark (Light Em Up)" will be released today via iTunes. It's the first single from their upcoming album, Save Rock and Roll, which will be released on May 6—that is also the 10th anniversary of their debut album, Take This To Your Grave.

Additionally, Fall Out Boy announced they will perform this evening in Chicago at Subterranean, tomorrow in New York City at Webster Hall Studio and Wednesday at The Roxy in L.A. Their formal tour will kick off on May 14.

If 2013 isn't the comeback year, then we're not sure what is.
