Lindsay Lohan joins Sam Ronson at The Estate

It's official. Lindsay Lohan plans to stand by her gal pal, DJ Samantha Ronson, at tonight's Winter White Party at The Estate, 1 Boylston Place.

Ronson will spin while her crimson-haired girlfriend will host the evening kicking off at 11 p.m. and lasting until 2 a.m. Doors open at 9 p.m.

Before heading to The Estate, Ronson and Lohan are slotted to stay at the Liberty Hotel and are expected to dine at Scampo.

The duo, who reportedly had a falling out during their big New Year's Eve bash sponsored by SoBe Lifewater at Miami's Mansion, were back together at last Sunday's Declare Yourself "Rebirth of Citizenship" inauguration event in DC.

Lohan responds to the break-up "rumors" surrounding Ronson on her MySpace blog here. "Get your stories straight please," she shoots back. "It's really annoying to have all of your friends e-mailing you saying, i saw, i read, etc... NOT TRUE."
