Since she started dating Samantha Ronson, Lindsay Lohan has been nearly unrecognizable.

She doesn't fall down drunk, she doesn't make outlandish statements and she almost always wears underwear. It's a totally different Lindsay than the Firecrotch Queen celebrity gossip tabloids fell in love with.

Fortunately, while walking the streets of L.A. over the weekend, the old Lohan flashed a bit of her former self... by flashing her nipples.

Indeed, a see-through shirt + no bra = the Lindsay Lohan we know and love!
