Bush rocker Gavin Rossdale and 30 Rock alum Jack McBrayer seem unlikely friends, but they’re actually really close.

“What’s so sweet about Jack — I’ll give you a fun insight to Jack,” Rossdale explained on Monday’s episode of Jesse Tyler Ferguson‘s Dinner’s on Me podcast. “Since I’ve got divorced and was raising the kids on my own, he’s come to every Christmas and Thanksgiving that I do with my kids. He comes to them, and so we just had him for Christmas, we had him for Thanksgiving, and he, the last Thanksgiving, he sent in — I posted it on my Instagram a little while ago — but he sent me an invoice.”

McBrayer’s bill, Rossdale clarified, was “for his presence.”

Listen to the full episode below. They begin talking about McBrayer at about 37:30 into the conversation.

Rossdale and Gwen Stefani, his wife of nearly 13 years, divorced in 2015. They share three sons: Kingston, 18; Zuma, 16; and 11-year-old Apollo.

The “Glycerine” singer said he felt bad for his kids in a visit to the Amy & T.J. podcast in March 2024.

“That would be the most profound thing, of, like, I wish I could have just figured out a way to not have that in their lives,” he said. “It wasn’t fun for me to be from a broken home. I think in a way it gave me a career so I don’t mind, because I turned it around into sort of an interesting career path, but it can be quite debilitating for kids…. The overriding thing is like, you don’t want to let your kids down.”

McBrayer came up during Rossdale’s conversation with Ferguson when the Modern Family alum complimented him on the first few guests he’d had on his cooking show, Dinner With Gavin Rossdale. The list included McBrayer, whose other credits include Forgetting Sarah Marshall and Wreck-It Ralph.

Rossdale described him as “the best” and “a really good friend of mine” who’s “been helping me a lot recently do all my auditions” for shows and movies. He joked that McBrayer is “a horrible director, because I haven’t got one.”
