Channeling her inner-shopaholic, Lindsay Lohan was spotted doing a little retail therapy on Melrose Avenue in Los Angeles yesterday (September 1).

The "Mean Girls" actress looked a bit annoyed at the paparazzi presence as she made her way inside Chuck's Vintage Clothing Store, sporting a sexy black and white top sans bra with black stretch pants and black boots.

And it sounds like Playboy isn't willing to take no for an answer- the gentlemen's magazine has reportedly offered LiLo $900,000 to pose for them.

Last year, Hef's publication offered $500,000 and Lindsay turned them down. But with the new almost-doubled paycheck, it'll be interesting to see if she stands her ground.
