How did 18-year-old Nick Prugo manage to allegedly burgle Lindsay Lohan's house so easily? Well, breaking in is easy if you're friends with your target – which is exactly what TMZ alleges.

According to several people who worked on Labor Pains, Lohan's painfully bad, straight-to-basic-cable movie, Prugo was a frequent guest of the actress on set. And not in a one-time, Make-A-Wish-Foundation kind of way – one source told TMZ that they had seen Prugo and Lohan together at least ten times. They were probably just sharing their inner most secrets, like where Lohan's safe was located and which doors she usually leaves unlocked.

Prugo was arrested last week on charges stemming from the Lohan break-in, among others. He was previously arrested in February for cocaine possession and was busted last month for DUI. Wow, now his friendship with Lohan makes a lot more sense.
