After several stints in rehab, it looks like Lindsay Lohan is finally getting her act together. Except there’s one thing that still riles up the actress: her obsession over her ex-girlfriend, DJ Samantha Ronson. According to the New York Post’s "Page Six," LiLo bought a house in Malibu next to Samantha’s. And last week she was in the lobby of the Four Seasons Beverly Hills hotel in the same day that Ronson was there.

* Sources say that Lindsay is after her ex-girlfriend and can’t stop pursuing her. Lohan’s often in the same places as her ex, almost every week. For Lindsay, it’s all just a coincidence. The actress told friends that she "had no idea that the house in Malibu was next door to Samantha’s" until she bumped into her on the beach. Yeah, right!

Lindsay Lohan: full of personal problems...
