Sober Party Girl Lindsay Lohan showed up at last night’s premiere of "The Tudors" reportedly because she’s friends with the Showtime series’ star Johanthan Rhys Meyers, who plays a hot King Henry VIII. But she hung with fellow on-the-wagon buddy musician Robbie Williams at the post party at Les Deux in Hollywood. The restaurant was decorated to resemble a medievel court with ladies-in-waiting, colorful canopied sofas and banquet tables. Because celebs really need more reasons to feel like they’re royalty. But relax, this is just a marriage of rehab convenience. Rumors are Lindsay is dating another mystery man and some say it’s Jude Law. Now there’s a match made in Unfaithful Heaven.
