Lindsay Lohan, who spent the weekend in New York, in the company of DJ Samantha Ronson, did not seem to like the attention her gal pal got from Ashley Olsen.

While partying with Samantha at Beatrice Inn and Hawaiian Tropic Zone, Lohan noticed Ashley greeted Samantha and couldn’t refrain from making a scene.

“Get your 15-year-old 'Full House' a-- away from my girlfriend,” reported a Page Six spy, who witnessed the scene.

Lohan was also upset Saturday, after her friend Samantha wouldn’t pay her any attention, being really preoccupied with spinning records, as Lohan was dancing and partying.

"Samantha was really focused on her work and didn't leave the booth for anything," the Page Six source added.

Lohan allegedly sat behind Ronson's deejay booth in the second level VIP section, and danced the night away until she left at about 4:15 a.m. in a black Cadillac Escalade.

Ronson and Lohan have long been rumored to be more than just friends, and Lohan is said to be so in love with her gal pal that she’s created a Facebook account under the name “Lindsay Ronson.”

People magazine reported Lohan might also have returned to her hard-partying ways. Recently out of rehab, she was spotted drinking Grey Goose vodka and Red Bull cocktails, while smoking cigarettes.

In the past months, Lohan declared she was struggling to completely recover, by abandoning bad influences and keeping trustworthy and caring friends close to her side.

But she was since drinking alcohol several times since rehab. In January, she was videotaped drinking champagne straight from the bottle, during her visit in Italy.
