Perhaps...(not saying it is fact) ...perhaps the the reason she felt the need to lie was she knew the way the whole think occured was abit dodgy...

perhaps the whole thing was concocted between her and her friend as a "fake" disagreement that they could then "sell" to the show and as a result profit from.
