National Enquirer: Reese Witherspoon and Ryan Phillippe might have split because of all that secret BlackBerrying and making out Ryan allegedly did with Stop Loss co-star Abbie Cornish behind a pulled curtain in an Austin, Texas, Asian restaurant.

Us: Ryan admitted to the affair when Reese confronted him and said it was time to end the marriage (though Cornish's rep still denies she has anything more than a professional relationship with Phillippe).

Star: Rumored to be suffering from an eating disorder, ultraslim Nicole Richie checks out of an $80,000-a-month rehab to go shopping. In her defense, she only spent 72 hours in the rehab and should have a $72,000 refund coming her way. Also, Angelina Jolie looks pregnant again! And Nicole Kidman parties, leaves Keith Urban and his ring behind.

OK!: Sensing an opportunity for renewed relevance, Mischa Barton and Richie ex DJ AM are supposedly helping the 85-pounder thicken up in rehab, the mag reports. Um, can someone tell Mischa, AM, and OK! that Nicole's left the building?

Life & Style: Nicole Richie didn't just check out of skinny rehab to shop—she checked out to, get this, party! Meanwhile, TomKat goes on a pre-nup diet. Good! Fat cows.

People: Katie has a new BFF, too, and it's none other than Tom's anti-depressant tirade target Brooke Shields.
