'Pitch Perfect' Co-Stars Anna Camp and Skylar Astin Get Engaged

— -- It looks like "Pitch Perfect" co-stars Anna Camp and Skylar Astin are making beautiful music together.

The two got engaged over the holiday weekend while vacationing in Kauai, Hawaii. They announced the news on their Instagram accounts, posting the same photo showing them smiling happily in a car with Camp flashing her new bling.

Astin, 28, wrote, "I asked. She said yes!!!" while Camp, 33, shared, "He asked. I said YES!!!!"

Camp called Astin her "best friend" in an interview with Glamour last year.

"We were friends first and just hit it off," she said. "He was dating somebody, and I had been through [a divorce] and he was like, 'Do you want to go on a date?' I remember thinking, Well, he's younger than me ... but I was like, 'You know what? OK! Let's do it, let's see.'"

Camp and Astin have been dating since June 2013.

This will be Camp's second marriage. She was previously married to actor Michael Mosley and the two divorced in 2013.
