Open mouth, invite gone.
Many were surprised over the summer when Adam Levine was not at Blake Shelton and Gwen Stefani's wedding, especially given how he's close with both the bride and groom. While appearing on Ellen DeGeneres' eponymous talk show on Dec. 6, Blake joked that the Maroon 5 singer never received the invite because of comments he made during a previous interview.

Earlier this year, Adam appeared on Ellen's show and humorously said that he would cause a ruckus at the wedding.
"That's the reason we didn't invite him to the wedding is that interview he did on your show," Blake laughed. "It's like, 'I'm not inviting him.'"
Adam further quipped in his past chat that he didn't support the union.
"She's so cool and he's not," he said. "I'll go to the wedding and I'll object. I probably won't be invited now that I'm saying this on live television. But I'll be there somehow."

On Dec. 6, Ellen asked the country crooner if Adam would have been invited had he not opened his mouth, Blake said, "Well, we'll never know. I purposely did not invite Adam Levine to my wedding — and I think it's funny."
In the end, the wedding — which took place at Blake's ranch in in Mill Creek, Oklahoma — was a very intimate affair. Blake estimated that, including wedding staff, less than 30 people were there.
"It was awesome," he said. "It was exactly what it needed to be."
