Lily Allen has returned to the United States to continue work on her second album. The pink-haired singer had some issues with her US visa last summer, following her attack on a paparazzo, but she managed to smuggle herself back into the country. Maybe they didn't recognize her with her new hair color. Now she's in Los Angeles and was seen here, enjoying a meal out with Ronson and Lohan.

As for Lindsay and Samantha, these two lovebirds had a spat over the weekend at Katsuya over dinner. According to a spy in the restaurant, "Lindsay kept ignoring Sam all night long as they ate. Then she [Lindsay] made a huge scene and stormed off." Hmm, I wonder why they could possibly be feuding...

However, it looks like they were back on speaking terms Monday afternoon, when Samantha showed up for an on-set visit at Lindsay's new movie, Labor Pains. That title sounds like it describes what it feels like to be in that relationship of theirs.
