Fans everywhere must be freaking out right now!

Justin Timberlake just answered the world's prayers by revealing he's open to collaborating on a song with his ex Britney Spears!

Just last month, Brit Brit was asked during a Q&A on Most Requested Live with Romeo who her "dream collaborators" would be, and she included JT on her list. "Aerosmith seems really good and bright. He's a genius I think. He's very rock n' roll. He sings from his soul. Gwen Stefani, I think she's great. Justin Timberlake is very good," she hinted.

When E! News correspondent Marc Malkin asked him if he would ever consider it, the "SexyBack" crooner confessed he wasn't aware of the "Piece of Me" songstress' comments, but he'd definitely entertain a collab. "She did? Sure! Absolutely, absolutely. I have a 17 month old so I don't get the headline news. I apologize for not being in the know…I'm accessible, give us a call!" he responded.

A Britney-Justin mashup would be the song of the century!
