The latest thing that the omnipresent socialite got herself involved in is the movie 'Bottoms Up'. Now, even if many would be tempted to believe that we're talking about yet another porn flick, because of the title, rest at ease that this is not the case.

But it is indeed a poor movie (and we're willingly understating the whole thing) that didn't even make it through the test screening and which will be released directly on DVD. The saddest thing (for Paris, of course) is that its launching is seen by one of her co-stars as the perfect opportunity to talk about her total lack of professionalism while on the set.

Simona Fusco, one of the actresses that stars with Hilton in the comedy (is that what it's meant to be?) says that the spoiled heiress almost ruined the movie with her incompetence. 'I don't think there's any talent there. My biggest problem with Paris was that she was always late on the set. It became very annoying. Everyone gets tired.', Fusco said about Paris' behavior during the shoot.

And the revelations just keep coming on, as Simona says that, although Paris arrived late for each day of the shoot, there was something else that bothered the cast of 'Bottoms Up'. 'By the time Paris showed up, she was usually coming from a party. She never memorized her lines. So now, not only does she show up late, but on top of it she didn't have her lines ready to go. It was a very long day working with Paris', the co-star concluded by saying about her not so joyous experience of sharing the same set with the socialite.
