Beyonce Knowles won't be the only Pepsi pitchwoman during Sunday's Super Bowl: One new commercial will star Kelly Osbourne, who, in turn, will be joined by Marie Osmond. Yes, really.

Kelly and the others in her loud-mouthed MTV clan will be featured in Super Bowl ads for Pepsi Twist that will be a continuation of the drink's special effects-laden earlier commercials, in which someone such as Halle Berry unzips herself to reveal Barry Bostwick.

The new spot, filmed inside the Osbourne home, features father Ozzy  and two of his oddball offspring, Kelly and Jack, bickering among themselves before the kids unzip their disguises to reveal their true identities: Marie and Donny Osmond.

Ozzy then sits up in bed screaming, as if it's just a nightmare, and looks at his wife, Sharon -- only to discover that she is Florence Henderson, TV's Carol Brady. Nightmare, indeed.

The Super Bowl is expected to attract a TV audience of nearly 87 million viewers, with ABC reportedly charging about $2.1 million for a 30-second spot. In fact, some viewers may be tuning in only to watch the commercials, which this year will also include a spot for Hanes T-shirts featuring Michael Jordan and Jackie Chan, among others.
