Skylar Astin is feeling most at home while filming "Pitch Perfect 2" due to his girlfriend Anna Camp. The third installment in the franchise, meanwhile, might bring in Taylor Swift.

Sitting with Nick Lachey for the "Big Morning Buzz," Skylar Astin was asked how it is filming with girlfriend Anna Camp.

"It's my girlfriend so it actually felt like a slice of home, having her down there," he said. "Love is powerful."

"When you respect the person that you're with, and I've always known her as an actress, it's pretty comfortable," he said.

Skylar Astin and Anna Camp, however, have no scenes together in "Pitch Perfect 2."

Meanwhile, Anna Camp told E! News that Taylor Swift should join their group for "Pitch Perfect 3."

"I think that Taylor Swift would make a great Bella. I really think she would. I think it would be an even bigger movie!" she said.

Skylar Astin added that one of Taylor Swift's hit tracks, "Shake it Off" would be a great song to do acapella in.

His girlfriend Anna Camp butted in as she said, "Well we'd have to sing 'Blank Space,' and have a whole 'Bella girl-power moment!'"

The couple also sees the Barden Bellas beyond "Pitch Perfect 3."

"I'll do Pitch Perfect 25!" Anna Camp said, before Skylar Astin added, "Yeah, we want to do like the old age home."

"I want to be old lady Aubrey, with my walker and gray hair!" the actress quipped.

"Pitch Perfect" writer Kay Cannon told The Hollywood Reporter that there's room for another sequel after the success of the second one.

"I'd love to see Chloe take the advice of letting go of her control issues. She's probably going to be a hippy. I do want to write the third one. I don't want to give over my baby to someone else. I would love to see Tracy Morgan in it. Not only because I think he's hilarious, but I miss him and want to see him perform again," Cannon said.
