It takes a keen eye to keep up with the ongoing soap opera otherwise known as Lindsay Lohan and Samantha Ronson's relationship. From restraining orders to Twitter spats, these two can't seem to keep their problems discreet.

Everything seemed peachy last week when the two were spotted lunching together at a Mexican restaurant before attending the American Idols tour. But on Saturday night, when LiLo headed to Hollywood's Playhouse club to watch Sam deejay, E! sources say the two didn't talk to each other at all.

Then came the big upset on Sunday night when Ronson went out for sushi at Nobu in Malibu with actress Drea de Matteo.

Ronson tried to calm speculation by saying the Sopranos actress was simply one of her "best friends." Unfortunately, this didn't deter people from calling the night a dinner date. Read: Can Men And Women Just Be Friends?

The news did not seem to go over well with Lindsay. Video cameras caught the redhead outside Ronson's house around 6 a.m. Monday morning, knocking on her door. Once she was let in, the cameras picked up audio of them arguing loudly. Lindsay did not re-emerge again, so perhaps it's safe to assume the quarreling lovers sorted things out.

After all, we're not sure there's anything to argue about: Matteo is actually engaged to singer Shooter Jennings. The couple have child together. So, uh, no worries, LiLo.
