Lindsay Lohan barred from Sam Ronson party?

Lindsay Lohan was reportedly barred from a Samantha Ronson DJ-ed gig, amongst fresh rumours the women have split up.

The couple have been largely inseparable during their year long relationship, with Lindsay accompanying Sam to most of her gigs - but according to onlookers at Bar Marmont in Hollywood on Friday, Lindsay was most definitely not welcome.

A source explained: “Lindsay knew she was unwanted, but came anyway, to no avail.

“[She was] restrained from coming in by five security guards.”

“Unless Lindsay rammed a truck through the red carpet or skydived in, she wasn’t [getting in there].”

The party was celebrating the launch of Sam’s twin sister Charlotte Ronson’s fashion like for JC Penney. As well as Sam behind the decks, their brother Mark Ronson and mum Ann Dextor Jones were also in attendance. Other guests included Nicole Richie, Paris Hilton, Sting and Jewel.

Yesterday workmen were spotted at Sam’s Los Angeles home, changing the locks on the doors.
