Lindsay Lohan really, really needs to know what time it is, if these reports are true: According to Celebuzz, the erratic actress spent upwards of $50,000 in 45 minutes at Beverly Hills' Phillipe's Watches & Jewelry this week. That included a $30,000 diamond-studded Rolex.

This isn't the only recent report of Lohan's extravagant spending habits. OK says the starlet spends about $800 getting her hair washed and blown out each week, and pays about $500 for Samantha Ronson to keep up her choppy mop.

We have to wonder where these seemingly endless funds are coming from. Her leggings line? Personal appearance fees? Or maybe she's banking on a sequel to "I Know Who Killed Me"?
