Distance may make the heart go fonder, but for Lindsay Lohan and Samantha Ronson, proximity seems to be the key.

After finishing her 90-day rehab stint at the Betty Ford Center in January, Lohan, 24, moved into a four-bedroom Venice, California beach house next door to her old gal pal and now it looks as if the twosome are rekindling their sometimes volatile on-and-off romance.

Friday morning Ronson, 33, suggested on her Twitter account that the pair had shared a sleepover.

"Watching grey's anatomy -- my fav show -- @lindsaylohan sleeping next 2 me -- should I wake her up to let her know her mom is going on GMA?" she wrote.

The pair, who have had several break-ups and make-ups since they started dating in 2008, also shared several flirty tweets back and forth on Valentine's Day, including one where the actress told Ronson to "have fun" at her DJ gig at local bar, The Brig.
