Lindsay Lohan — Bikini Pics Reveal Nasty Bruises

Exclusive 0402_lindsay_lohan_brazil_bikini_launchLindsay Lohan threw on her bikini and hit the beach in Brazil yesterday … revealing a series of gnarly bruises down her left leg.

It”s unclear how Lohan got her new marks … it”s possible she just banged herself up while ducking under tables at a nightclub last week.

Then again, it”s not impossible to think she got into another late-night altercation — just ask that psychic she allegedly socked in the face a few months ago.

As for LiLo”s bikini top … Amtrak called, they want their curtains back.
