Samantha Ronson performs a sexy lap dance for Lindsay Lohan.

The DJ treated her ‘Mean Girls’ star girlfriend to the saucy
routine as Katy Perry hit ‘I Kissed a Girl’ was played.
Samantha – who is the sister of music producer Mark Ronson – gave the
impromptu erotic dance after becoming jealous of other girls flirting with
Lindsay.
A source said: “They went into a full kiss, their hands all over each other.
Nobody knew where to look.”
Earlier in the evening, 22-year-old Lindsay had ordered several girls away
from Samantha’s DJ booth after she spotted them handing over their phone
numbers written on the back of drinks receipts.
The source added: “Lindsay crawled on all fours under the bar and nestled up
to Sam on the decks, hugging her as if to say she was her girl.”
Lindsay’s ex-boyfriend Calum Best – the son of late soccer legend George
Best - was also at the event, but kept his distance from his former lover.
As the stars left at 4am, a fight broke out outside, prompting Lindsay’s
minders to desperately fend off fawning fans.
Lindsay said: “I’m OK, I’m a big girl, I can take care of myself.”
She added of the chaos: “I just wanted to make sure everyone had a good
time. I didn’t want anyone to get hurt. I’m so, so sorry.”
Lindsay and Samantha are reportedly set to fly out to Paris today to have
two engagement rings made based on their own designs.
They are expected to return to the UK to make an official announcement
