Paparazzi photo agency X17 online presents Jessica Simpson’s timeline on the night that she was said to have hooked up with John Mayer at the Four Seasons, as reported by TMZ and gleefully repeated here. She didn’t get back to her room until 1:30 AM, and was seen leaving club Hyde with producer James Krisel. Commentors note that if she was dating Krisel she would have on her corpse makeup and would have worn her hair down.

It’s possible that she got busy with Mayer once she returned to the hotel, and it looks like X17 is just saying it must not have happened until early in the morning according to their spies:

* 10:17 PM: Jessica arrives at the Sunset Marquee hotel on Sunset Blvd* 11:50 PM: Jessica arrives at Hyde with producer James Krisel* 11:50 PM -1:00 AM: FURIOUS DANCE PARTY ACTION ACTION ACTION (presumably) in the club* 1:00 AM: Jess and James leave Hyde together – as you can tell from these pictures, they were more than a little camera shy!* 1:50 AM: Jess arrives at the Four Seasons where she supposedly hooks up with Mayer, according to TMZ.com

It seems like hotels are bad news for young celebrities like Simpson and Lohan. They make the decision to party at high-profile clubs and stay in hotels, and everything they do becomes public. Of course that’s where all the action is, but if they hook up with someone it’s quickly going to become gossip news.
