Melissa McCarthy, Adam Levine: 'St. Vincent' Actress Talks About Crashing 'The Voice' Star's Halloween Party On ‘Jimmy Kimmel Live!’ [VIDEO]

Could Aunt Bernice be a new character in an upcoming Melissa McCarthy movie? If so, we'd see it! The St. Vincent star stopped by Jimmy Kimmel Live! just last night to talk up the new Bill Murray-led film. During her segment, the ABC host pulled out a throwback photo of the actress alongside Jennifer Esposito at one of Adam Levine's (The Voice / Maroon 5) Halloween parties –– which she claims she was invited to out of pity.

"That's my idea of Halloween, right there," says McCarthy, pointing to the picture of her dressed as her Aunt.

According to the Mike and Molly star, she used to live on the same block as the Maroon 5 frontman. "Which was a pretty good thing," she joked. One year, the band threw a massive Halloween party, which her and her husband, Ben Falcone, were invited to... just so they wouldn't call the cops. And while they decided to go, it seems that her costume choice wasn't quite on par with everyone else who attended. In fact, it horrified them!

"Every single woman was in a different kind of bikini," the actress said. "'What are you?' 'I'm a cave girl...' in a bikini. 'I'm a medic.' ... Just two crosses and a stethoscope."

MCarthy then joked that every girl would ask her, "What are you?" And for some reason no one guessed Aunt Bernice.

Check out the full segment below.

As Kimmel said, "Watch out," referencing a Halloween party being thrown by The Voice star this year. "Aunt Bernice is coming for you!"
