(Cover) - EN Showbiz - Samantha Ronson has reportedly been "flaunting" her rumoured new beau in front of her ex girlfriend Lindsay Lohan.

According to sources, the DJ has been romancing Erin Foster for a couple of months, and has been deliberately hanging around Lindsay's favourite Malibu spots in a bid to make her jealous.

Lindsay, who recently turned 25, was released from house arrest last week and is enjoying her new found freedom. The troubled actress served 35 days in home confinement stemming from her conviction for stealing a $2,500 necklace from a jewellery store in January.

Since her release, the star has been celebrating her birthday and the July 4 holiday in the area with friends, and according to sources, Sam has also been hanging out in the same places.

A source told X17 Online that Sam has been "flaunting [Erin] around, where Lindsay always hangs for the 4th of July weekend."

The source also added that "Sam is fed up with Lindsay and is doing this to make her jealous."

It was previously reported that Lindsay was "heartbroken" over her ex's new girlfriend and that she's "madly jealous" of Erin.

Lindsay and Sam split in 2009, but the star never seemed to have fully gotten over ex lover - moving next door to the DJ's Venice home. (C) Cover Media
