No bra, what a shock

Lindsay Lohan's hooked up with so many people in her life, she can't go to a club without running into one of her ex-flings -- male and female. The latest run-in occurred last month at the grand opening of Apple Lounge in West Hollywood. A witness at the club told In Touch Weekly:

"Lindsay chatted with her ex Harry Morton for a few minutes. Sam wasn't thrilled."

Lindsay, 22, was there to support her live-in galpal, who was deejaying the event. But before the night was over, another of Lindsay's exes, Calum Best, showed up, followed by former girlfriend Courtenay Semel. Although Lindsay's rep says, "It wasn't awkward for her to be with all of her exes," a witness says, "That was definitely enough drama for Lindsay. She made sure the rest of the night was very mellow, drinking little as she smoked and stuck by Sam's side . . . Lindsay reassured Sam by gently rubbing her lower back whenever they were alone."

Courtenay Semel dated Lindsay in late 2007, says an insider. Lindsay dated Calum Best for three months in 2007. Harry Morton romanced Lindsay in 2006.

Is anyone surprised Lindsay ran into a couple of her exs while out and about in Hollywood? That slut's screwed more people in Southern California than la migra. About the only place Lindsay could hang out where she wouldn't run into someone she used to "date" is Lance Bass' house.
