Britney Spears starred in a Pepsi ad during last year's Super Bowl.
It's thought she got more viewers than the game itself!
This year, the company are hoping to go one better with the ad for their new lemon drink, Pepsi Twist.
After Jack and Kelly turn into the Osmonds, Ozzy screams his now-familiar "Shaaaaarrrroooooooooonnnnnnnnnnnnnnn"!
But Ozzy won't be that angry - Britney's rumoured to have been paid £5.7m for her starring role in 2002.
