Paramore's Hayley Williams and New Found Glory's Chad Gilbert had a really special New Year's Eve -- they announced that they're getting MARRIED!

The couple revealed their engagement on New Year's Eve via social media - days after Gilbert popped the question on Christmas Day.  A photoshopped image shows the rockers decked out in wedding attire with the words "Getting Married" splashed across the photo.

Williams added via Twitter that they were both "psyched" and looking forward to seeing everyone in the new year.

The couple has been dating since 2008, and in celebration of their engagement, Hayley shared an adorable throwback photo from when she and Chad first started dating. 

Cutest. Couple. EVER.

Congratulations to Hayley and Chad!
