Lindsay Lohan made her way to Samantha Ronson's house last night after dinner with friends at Matsuhisa in LA. Samantha is back home after a quick trip to London to see her brother Mark, and she missed out on some of the wilder parts of Lindsay's 23rd birthday weekend. Life with Lindsay is rarely dull, and the latest drama is that she's being sued for allegedly stealing the formula for her Sevin Nyne tanning spray.
