It's been a few weeks since we've seen Lindsay Lohan with her once-BFF Samantha Ronson, and apparently LL's found herself a brand new sidekick. She grabbed some lunch at La Scala on Monday with Courtenay Semel, who you may remember from the reality show about rich kids at a cattle ranch. Courtenay's daddy is Terry Semel, the Hollywood big-shot who most recently was the CEO of Yahoo. Supposedly the two girls have been inseparable in the past few weeks, hitting up parties together and maybe even living together. As long as Lindsay stays out of trouble, we're all for her making some new friends. Besides, it's better than her hanging out with her annoying parents.
