The 'Pitch Perfect' stars have revealed they are set to tie the knot after Skylar got down on one knee over the new year.

Captioning a picture of the pair where Anna is showing off her sparkling ring, he wrote: "I asked. She said yes!!! (sic)"

To which, she added in her own post: "He asked. I said YES!!!! (sic)"

Meanwhile, the 33-year-old actress previously revealed the pair are the best of friends.

She gushed: "The funny thing is, is that we never ever have any scenes together. So, yeah, it was great. We had a great time when we saw each other on set. It was awesome. We're really best friends, so it's awesome. He's definitely sweet like his character is."

Skylar was also a support for Anna when she split from her now ex-husband Michael Mosley, with an insider revealing the pair have always had "amazing chemistry".

A source said at the time: "They had a great connection and became friends, but nothing romantic happened until after she separated from her husband. They have amazing chemistry."

The couple - who are best known for their roles of Aubrey Posen and Jesse Swanson in the musical movies - have been dating since 2013.
