X17 EXCLUSIVE - Lindsay Lohan Leaves Samantha Ronson's House At 4am With "I Love You" Bear

Lindsay Lohan left ex-girlfriend Samantha Ronson's house early Monday morning clutching a teddy bear with the words "I love you" written on it, just days after Samantha was caught in a lip lock with another woman.

Lindsay walked over to Sam's house (which is just next door) at 11pm Sunday night. Lilo stayed until 4am, when she returned to her own pad proudly displaying her new bear, which seemed to be a gift from Ronson.

An X17online photographer on the scene tells us:

"It was pretty late but Lindsay didn't look tired at all -- she was beaming! With all her court and family drama going on she still looked happier than she's been in a long time. It was almost like she really wanted to show off her new little toy, which must have been a gift from Sam."

Lindsay was furious after she saw photos of Sam smooching a cute brunette in her Porsche over the weekend.

She even tweeted her dismay to her followers, saying "Funny how I just dropped @samantharonson @lax" with a link to the pix.

But Samantha is apparently desperate to make up with her ex-girlfriend and current neighbor, giving Lindsay the cute bear as an apology.

Samantha and Lindsay have had an on-again, off-again relationship for years. Even though they aren't technically together anymore, after Sam was initially upset that Lindsay was moving in right next door to her in Venice, the girls have gotten friendly again. The pair have been seen out together numerous times and Lindsay even gave her ex a ride to the airport!

Are these two headed for a full-on reunion?
