Britney & *Nsync storm McDonald's

Britney Spears and *Nsync drew huge crowds as they serenaded fans at McDonald's over the weekend.

Britney and *Nsync were shooting a commercial for the fast food chain in Vancouver on Saturday, and hundreds of fans showed up to catch a glimpse of the record-breaking pop stars, the Vancouver Sun reports.

Three hundred local pop-lovers between the ages of six and 14 were hired to play excited fans, as Britney and the boys of *Nsync pretended to perform "Bye,Bye,Bye" and "Oops! ... I Did It Again" under the golden arches.

Parents of the extras got to wait for their children behind the local gas station.

"It was pretty hectic around here," said Will Legaree, a station attendant. "Between all the crew and security guards and all of the extras and parents, there was probably 450 to 500 people here."

Pop fans continued to visit the location on Sunday but found that Britney and *Nsync were already gone.
