Lindsay Lohan’s got it bad. The twenty-one year old reported lesbian is back on the booze and ready to pounce anyone who glances at her record-spinning GF, Samantha Ronson. Actress Ashley Olsen was first to experience the wrath of Blohan when she dared to say “Hello” to Ronson during the DJ’sset at The Beatrice in Manhattan last Saturday night.

“Ashley Olsen said hello to Sam at the Beatrice, and Lindsay screamed at her, ‘Get your 15-year-old ‘Full House’ ass away from my girlfriend,’ “ says a Page Six snitch.

Saturday, Lohan said Ronson “was ignoring her” and became upset. “Samantha was really focused on her work and didn’t leave the booth for anything.” Lindsay is so into her pal, she’s even created a Facebook profile under “Lindsay Ronson.”
