Lindsay Lohan celebrated her 22nd birthday last night at Teddy's Lounge in Hollywood with a prom-themed bash for 50 guests, reports People.
Lohan wore a pink strapless mini and a huge diamond necklace, and was accompanied by DJ girlfriend Samantha Ronson, who wore black pants, a tuxedo shirt, bow tie and top hat, and never left Lindsay's side.
Just after midnight, a cake was presented featuring a pic of Marilyn Monroe. Earlier this year, Lindsay memorably posed as Marilyn for New York magazine. Then Sam took over DJ duties, and LiLo made several visits to the booth, even sneaking in a kiss.
