Britney keeps stars waiting

The superstar trio were at the National Gallery in London's Trafalgar Square for the first screening of the multi-million pound promo.

In it they play gladiators while pop heartthrob Enrique Iglesias is an evil Roman emperor.

Last night's glitzy event was of the sort usually laid on for a Hollywood movie premiere, not a three-minute fizzy drink commercial.

But with the combined star power of Britney, Beyonce and Pink, it is one of the most hyped TV ads in history.

Britney was last to arrive, keeping her fellow stars waiting for 10 minutes.
Wrapped up against the bitter cold in a black Dolce & Gabbana coat, the 22-year-old singer said: "To have this premiere is pretty amazing.

"Filming the ad was awesome, it made me feel empowered and I got to work with these two fantastic gladiator women."

Asked about her recent marriage fiasco, Britney said: "I've reached the stage now where I can laugh about it."

The star married childhood friend Jason Alexander in Las Vegas earlier this month but she instantly regretted the decision and the marriage was annulled two days later.

Beyonce wore a fur jacket to walk down the specially laid blue carpet, while Pink went for a more theatrical look in a black top hat.

The trio have reworked the old Queen hit We Will Rock You for the ad and band members Brian May and Roger Taylor were also at the event.

After a screening of the ad, Britney, Beyonce and Pink moved on from the National Gallery to the Dominion Theatre, home to the Queen musical We Will Rock You.

The audience was made to wait over an hour for the show to start because the girls were late arriving.

When they did finally turn up, they stood on stage with Brian May and Roger Taylor, then left without a word after less than a minute.
