Sorry Britney fans!

Although Britney Spears still looks incredible, the sexy bikini picture she tweeted the other day is, it turns out, from 2008.

"Y'all ready for summer to end? I'm definitely not!" the singer wrote under the photo, which is from the same set as the image used on a 2008 OK! cover. (In it, a blonde, tanned Spears, now 30, rocks a bright white bikini, huge sunglasses, and a massive smile.)

Fans began to suspect something was up when Spears made no mention of when or where exactly the sun-soaked image was taken.

Regardless, the X Factor beauty managed to prove she's still got it in a separate picture posted Tuesday. In that shot, Spears, wearing a stunning little black dress, poses in front of a flower bed for a Happy birthday message to one of her family members.
