Hours before Lindsay Lohan checked into a rehabilitation facility in Southern California, she was frantically trying to keep tabs on ex-girlfriend Samantha Ronson, who lives in the same West Hollywood apartment complex as the troubled actress.

Samantha left the building around 9pm and headed to the W Hotel in Hollywood, and we're hearing Lindsay texted photographers and asked where her former flame was going, and get this -- she also begged them to follow her! Given Lindsay's relationship with the paparazzi (ahem, you know those reports of her asking $10,000 for staged shots of her SCRAM bracelet) we totally believe it, and this isn't the first time we've heard of her taking desperate measures to follow the DJ...

Maybe she just wanted to have one last chat before she was sent off to rehab for the next 4 weeks? Think Sam indulged her?
