Former lovers Samantha Ronson and Lindsay Lohan got into a nasty fight last week, and ended with Lohan throwing a drink in DJ Ronson’s face!

A source says  “Sam was working her usual weekly gig DJing at Crown bar. Lindsay turned up around 11 pm and she was in the mood for trouble!

“Lindsay was drinking straight out of a bottle of vodka and I saw her take an orange prescription bottle out of her bag and pop a couple of pills that she said were Adderal, she even offered some of the pills to a friend that was with her.

“Lindsay was trying to get Sam’s attention, but she was working and studiously ignored Lindsay. You could see Lindsay getting more and more worked up the more Sam didn’t pay her any attention. At one point Lindsay was dirty dancing with this really pretty girl right in front of Sam, obviously to try and make her jealous.

“Sam just got sick of it all in the end though and started taunting Lindsay about her being all drunk and messed up. She said to Lindsay, “Why don’t you just have another drink?” and even told her, “You’re a disgrace”.

“That made Lindsay just totally flip out on Sam. She picked up a drink and threw it straight in her face! Sam was absolutely furious and picked up some DJ equipment that was by her and threw that at Lindsay. It was crazy!

“Lindsay’s friend grabbed her and pulled her away before things got even worse, she was losing control. It took her ages to calm down and she was going off about Sam for ages.

“Lindsay just has absolutely no self control when it comes to Sam. She obviously still has feelings for her and she’s totally not over her. It’s a completely toxic situation.”

Samantha told an L.A. radio station (AMP 97.1’s Stryker)  she was recently tossed from a club because “a certain somebody” was tossing cigarettes at her all night.

When asked if it was her ex — who she reunited with earlier this week — Sam said “I can only guess.”

Jennifer Aniston flew into Cabo San Lucas, Mexico, over the weekend with some riends, including Gerard Butler, Courteney Cox and Sheryl Crow.

They celebrated her upcoming b-day; she turns 41 on Wednesday (Feb. 11).

Aniston showed some skin in a brown and pink bikini ensemble while on the getaway at the One & Only Pamilla Resort.

She and Butler, her co-star in the comedy The Bounty Hunter, got cozy backstage at the Golden Globes last month.

Lady Gaga explained why she wasn’t at the “We Are the World” taping last week and said that she had never planned on being involved with it in the first place.

Gaga said: “I’ve actually been in rehearsal for my new tour, but I was never supposed to do ‘We Are the World.’ So that’s a rumor. I believe that they may have asked about it, but I was unable to do it.”

“Besides that, I’ve been working on my own charity projects for Haiti. We’ve raised over half a million dollars for Haiti already and we like to work specifically with charities that are based in Haiti itself. I donated all of the proceeds from one show worth of ticket sales as well as all of the merchandise from that show and for 24 hours we had a ‘Gaga for Haiti’ day where everything that was bought on the Web site. Every dollar went to Haiti. We’re continuing to work on more projects and we’re supposed to go to Haiti later this year for a show, which is very exciting.”
