Anna Camp, fiance Skylar Astin throw joint bachelor party

LOS ANGELES, Aug. 15 (UPI) -- Anna Camp and fiancé Skylar Astin combined forces for a joint bachelor party Saturday.

The Pitch Perfect co-stars, who got engaged in January, celebrated with their friends at a country-themed bachelor/bachelorette bash with dancing and karaoke.

"Nailed it," Astin captioned a photo of himself kissing the 33-year-old actress. Camp also shared pictures from the fête, including a snapshot of herself line dancing.

"And that's a wrap on the greatest weekend ever celebrating true love and happiness!" she later wrote. "Thank you to all the wonderful friends that helped put a smile on my face. I love you all so much."

Camp and Astin played Aubrey Posen and Jesse Swanson in Pitch Perfect (2012) and Pitch Perfect 2 (2015). The actress gushed about their romance when she spoke to E! News prior to the sequel's premiere.

"The funny thing is, is that we never have any scenes together," she said. "We had a great time when we saw each other. It was awesome."

"We didn't actually start dating for a while," the star revealed. "We're really best friends, so it's awesome. He's definitely sweet like his character."

Camp, who is also known for Mad Men and The Mindy Project, will appear in the new Netflix movie The Most Hated Woman in America. Astin is slated to star in the new Epix series Graves.
