The news all '90s kids have been waiting for!
Fans are speculating that Britney Spears and Christina Aguilera recorded a duet after a Twitter user shared an image from APRA (Australian Performing Rights Association), in which both singers are listed as performers on Britney's "Do You Wanna Come Over," a track from her latest album Glory.
Twitter user TheChristinaVIP shared the photo Tuesday and captioned, "Here's a conversation starter. Not sure what this means but it certainly made me say WTF?! What are you up to [Christina]?"
Christina, naturally, didn't reply to the tweet, but that didn't stop fans from going absolutely nuts on the tweet's thread.
"Guys, this could be EPIC!" said one fan, while another added, "Please let this be true!"
The last time we saw the popstar rivals share a stage was in 2003, as they accompanied Madonna for a memorable — and controversial! — performance at MTV's Video Music Awards. Both Brit and Christina locked lips with the icon during the sexy routine.
