Lindsay Lohan is Back in LA, and Still Ruining Lives

She's baaa-aaack! That's right, the Lohan has landed, and her first stop back in LA was a shopping trip to Robertson Blvd., where Linsday was "unexpectedly" mobbed by the paparazzi. And I can't be sure, but I think one of them may have copped a feel... I know I would have. Oh, and I think there's some nipple showing through in that top picture!

But Lindsay's landing in LA isn't the only story to tell. It seems as though her reputation as a homewrecker is more deserved than we thought. Lindsay has already caused one divorce while in rehab, and now she's ruining another relationship. According to Us Weekly, her new boyfriend, Riley Giles was actually engaged to a girl back home, before he met Lindsay in rehab. And not only that, he's already taking Lindsay out to bars (as if she needs much coaxing).

Us has learned that her new beau, Riley Giles -- a snowboarder she met during her two-month stay at the Cirque Lodge treatment center in Utah -- has a messy past.

Until recently, he was engaged to Murray, Utah, resident Bree Tierney. "Riley just stopped calling Bree and never told her about Lindsay," Bree's mom, Tess, tells Us. "She found out by seeing photos. It destroyed her."

Seconds a source, "Lindsay may be in danger with Riley." The concerns may be warranted: Giles escorted Lohan to the Hotel Bar & Nightclub in Salt Lake City on October 5 -- the same day she checked out of rehab.

Though one witness claims that Lohan drank that night, owner Jordan Harwood insists to Us, "Her group made it clear they didn't want any alcohol at the table."

Dumping a girl through the tabloids? That's cold. But I defy anyone to resist Lindsay Lohan shaking her tits in your face while you try and deal with getting over a drug addiction. Of course, if getting over a drug addiction was actually your goal, you'd run as far away from Lindsay Lohan and her boobs as you possibly could. But where the fun be in that?

Here's Lindsay in LA getting crushed by the paparazzi.
