Someone has hacked into the Twitter account where Britney Spear's people pretend to be Britney Spears, and pretended to be Britney Spears:
“HI Yall! Brit Brit here, just wanted to update you all on the size of my vagina. Its about 4 feet wide with razor sharp teeth.”
The team apparently knew this was a fake straight away - probably the correct spelling was a clue; the message has since been removed.
For some reason, "experts" have decided this hackage was probably done by the same person who hacked Barack Obama's account - presumably because that time the message read "It's Barack here, my vagina is four feet wide with razor sharp teeth."
