The cast of 90210 got together for a celebration in Beverly Hills last weekend. The gang was celebrating the release of the show's first season on DVD - can you believe that was 16 years ago? Brenda and Dylan were the only key members of the clique missing, and the cast members talked a lot about how they are still all like BFF. Pregnant Tori even showed off her growing belly at the bash. Here's more:

"We always worked hard to stay together as a cast," Jason Priestley, a.k.a. Brandon Walsh, told USA Today. Priestley was joined by a five-months-pregnant Tori Spelling, who played Donna, along with Jennie Garth (Kelly), Ian Ziering (Steve), Brian Austin Green (David) and Gabrielle Carteris (Andrea).

Garth, 34, said, "I wanted to support the show that gave me all I have this day." Plus, she added, "I didn't want to be the one who didn't come."

Spelling, 33, arrived about an hour after her costars, and told PEOPLE that since she's been pregnant, she's been learning new things every day. "Things that you never knew you'd take interest in," she said. "I'm just excited to have a family." The nausea and fatigue she experienced during her first trimester are almost gone, she said, and she's looking forward to starting prenatal yoga and Pilates.

I think Brian (Austin) Green should win most improved award. He looks fabulous! I wish his show with Freddie Prinze Jr was still on. I enjoyed getting a weekly fix of Brian. Isn't it cool that they are all still friends? The Melrose cast also released their first season DVD Friday night. More pics from the event so
