From In Style's Karen Levy and Ali Forman in Los Angeles: Getting into a shuttle at UCLA the other night was like a flashback to our college days. Only this time—thank God!—the shuttle was not dropping us off at a history class.

Instead, it was Music 101 all the way as we headed up the hills to a Bel-Air estate—this year's home to the annual William Morris Agency Grammys party. We had no idea who to expect but instantly felt at ease when we walked in the door and immediately ran into three friends—Melissa Holloway from Fox Searchlight, Untitled manager Evan Hainey and William Morris talent agent Nicole David, who represents lots of musicians, including Whitney Houston and 50 Cent. Melissa, just back from the Writers Guild Awards (where the Fox Searchlight film Little Miss Sunshine had won yet another statuette) was thrilled but also admitted to being relieved that awards season will soon be over. She has been working like a maniac.

Speaking of maniacs, there was some major dance mania going on in the library, where Prince was holding court with about 20 friends, who took turns hitting the dance floor while DJ Adam 12 turned the tables. Prince must have liked the music, because he ended up cutting a rug with P. Diddy and Terrence Howard, who also seemed to have caught dance fever. Tearing ourselves away from the dance action, we took a lap around the party to see if the rumors of hot dogs were true.

Outside, there was more A-lister action on the tennis court, which had been tented and filled with cozy circular lounge furniture. First spotted: Entourage's Kevin Connolly (which we thought might mean that Leo DiCaprio was nearby, considering they were childhood friends and still hang out together). Sure enough, the baseball cap-clad Oscar nominee soon appeared—in his usual cool and ultra-low-key mode. But when Diddy made a beeline for Leo to give him a hug, traffic pretty much stopped as everyone took time out from being cool in order to gawk.

Gwen Stefani and Nelly

On the other side of the tent, a very sophisticated-looking Gwen Stefani and hubby Gavin Rossdale were hanging out with rapper Nelly. Scarlett Johansson, looking chic in a sexy black minidress, had been a presenter at the Grammys and was tired from the long night, so she left early. But we heard a rumor that Prince had requested to meet her. Hmm ... wonder if that ever ended up happening.

We also ran into music producer David Foster, whom we hadn't seen since last July, when we were at his house—uh, we mean mega-mansion—for a different star-studded music event: Starry Night, a charity benefit whose guests included Oprah, Clive Davis and the Donald.

Now about that hot-dog rumor. Pink's Hot Dogs, a late-night munchies spot off La Brea Blvd., had set up a station where guests could get their famous chili and cheese dogs.

Yum. Nothing beats a 3:00 a.m. hot dog after a party! Once again, we felt like we were back in college.
