Adam Levine's getting dragged for his cheating scandal, but as he gets ready for a big gig in Vegas ... he's getting strong support from the man throwing the event ... Shaquille O'Neal.
Shaq tells TMZ Sports ... Adam is still good in his book, despite the Maroon 5 frontman's alleged infidelity, because Adam's always done charity work for children in need.
Adam and Maroon 5 are getting set to perform this weekend at The Shaquille O'Neal Foundation's annual fundraising gala, "The Event" in Las Vegas .
