How I Met Your Mother executive producer Carter Bays says Britney Spears is always welcome back, PEOPLE reports.

“We always said, ‘You know, if her character pops, we’ll bring her back.’”

“I thought she was great. I was very proud of that episode.”

“It was totally weird,” Bays said of having Spears on the set. “I think we have a very, like, kind of Midwestern homey vibe here on the show, and it was strange to suddenly have helicopters circling.” he said.

So, will Britney come back? “I don’t know,” he said. “I don’t know the answer to that.”
