• Party mom Dina Lohan better show up at her divorce court hearing this morning, or she'll be subject to "immediate arrest and imprisonment." Her ex, Michael Lohan, has reopened their contentious divorce case with new charges that she's drunk around their kids, and fails to show up to court-ordered visitations. Oh, and she wouldn't let him babysit his daughter's puppy. [Rush & Molloy]
• Dina kinda sorta outed Lindsay as a lesbian, just a week after Lindsay's dad kinda sorta did the same thing. It must be nice to have such great parents. [OK!] 
• Just a week after he was supposedly dumped by his fiancée Noelle Reno, Matthew Mellon already found a new fling. The banking heir and former husband of Jimmy Choo founder Tamara Mellon, has apparently found love with designer Nicole Hanley. [Page Six]
• Could Nick Cannon have gotten married to Mariah Carey for any reason other than true love? Judging from the new black American Express card he's been carrying around and the new Maserati he was seen test driving, the answer might be yes. [MSNBC]
  
• Sarah Larson may have been the only person who didn't see her split from George Clooney coming. The former waitress had moved into his LA manse and rented out her own Las Vegas pad, just before getting unceremoniously dumped by the star. Needless to say, she's not taking it well. [Marie Claire]
