Seriously? OMG! WTF?

The ad above aired during Standoff on Tuesday night after People announced the two were hosting the show. So I didn’t think much of it until yesterday when I was watching Bones and they ran another ad still saying that they are hosting the show. Fox denies that there is a host, but then why are they advertising that Britney Spears and Paris Hilton are hosting? I am so confused?
BTW sorry about the voiceover at the beginning and end of the ad, it was the only one I could find on YouTube.
