Yes

"Stop the bus a minute," the leader of the pack, a man named Randy, tells the driver as Kat checks out the bus, while Randy and the scores of men on the bus check her out.

"WHOA...check out the tits on the smoking brunette," one of the other guys, a loser named Ben, says as Randy invites Katharine onto the bus to the catcalls of the other men on it.

What Kat does not know is that this is not the party bus that it appears to be, although I guess you could say that it was a "party" bus of some sort.

All these men on the bus are actually a gang of prisoners who broke out of prison and stole the bus, and were hoping to use it to snag a hot girl to have their way with, which they now saw with her.

"Welcome aboard the party bus baby, my name's Randy, what's yours?" he asks Katharine as she climbs on board, the catcalls of the prison gang continuing.

"Oh come on, I'm sure you boys know who I am?" Katharine tells them, hiking up her dress to show a little leg, in addition to the tits she was already showing, "the name's Katharine McPhee. You've probably seen me on TV. Anyway, where's the party this party bus is going to?"
