Adam Levine & Maroon 5 Will Perform in Vegas Despite DM Scandal

Adam Levine isn't putting down the mic while he's in hot water over a DM mess -- he's still stepping into the spotlight on stage ... TMZ has learned.

Sources with direct knowledge tell us ... the singer is still scheduled to perform early next month with his band, Maroon 5, at The Shaquille O'Neal Foundation's annual fundraising gala, "The Event" in Vegas.

The gig is set to go down Oct. 1 at the MGM Grand, and we're told the show will go on -- even now, with Adam's relationship status in the headlines amid a DM scandal. Our sources tell us there will be no red carpet at the event, similar to last year, so Adam won't be grilled by reporters.

Not just that, but our sources tell us Adam is also going to forge ahead with other professional commitments he's already made -- and that would seem to include his M5 world tour, with stops all over Asia through the end of the year, as well as one final NYE show in Palm Springs.

It's interesting, considering the drama has now ballooned even beyond what was originally alleged. It all started with one woman claiming she had an affair with Adam, which he denied. She offered up DMs suggesting he wanted to name his unborn kid after her.

Although Adam denied being physically involved, he did cop to sending flirtatious messages and also expressed regret, while noting he's working it out with his wife, Behati Prinsloo.

More women have come forward with claims he was DM'ing them as well -- including some famous ladies alleging he attempted to DM them.

Adam and Behati were photographed together this week, but it's unclear where things stand between them.

At any rate, AL's plowing ahead with his frontman duties.
