Adam Levine has plans to 'object' Gwen Stefani and Blake Shelton's wedding

Adam Levine does not approve of his fellow voice coaches, Blake Shelton and Gwen Stafani's relationship.

Speaking on The Ellen DeGeneres Show this Thursday the Maroon 5 frontman said that he does not approve of his friends' marriage plans.

"I don't support their marriage," Levine began.

"She's so cool," the Girls Like You singer said of Stefani, "and he's not."

"But he's very funny and very smart," DeGeneres replied.

"He's vaguely charming," Levine went on, before laughing to himself.

"I'll go to the wedding and I'll object," said Levine. "I probably won't be invited now that I'm saying this on live television. But I'll be there somehow."

"I'll be your date. Let's go together," DeGeneres suggested.

"Let's go. Let's just crash," Levine added.
