Back on? Lindsay Lohan'sleeping next 2 me,'Sam Ronson reveals on Twitter

Lindsay Lohanmay be going through a rough patch, but she doesn't appear to be going through it alone.

The starlet's on-and-off relationship withSamantha Ronsonlooks like it could be on again.

Ronson, 33, prompted new speculation when shetweetedFriday morning that Lohan, 24, was"sleeping next 2 me."

According toTMZ.com, the former couple met up at the Roosevelt Hotel inLos Angelesaround 1:45 a.m. and, though they arrived separately, later left together.

They presumably went back to Ronson'sVeniceapartment– which is located right next-door to Lohan's.

Though the celebrity deejay was initially shocked when her ex moved there in early January, after Lohan's release from theBetty Ford Center, it seems they've worked out their differences.

Lohan and Ronson even spentValentine's Daytogether, but a source toldTMZthey"are just friends ... nothing more ... nothing less."

If Ronson's tweet is any indication, their relationship status may have changed.
