'Beverly Hills, 90210': Where Are They Now?

Aug. 19, 2010— -- Two months after giving birth to her daughter, Tiffani Thiessen returned to work this week on the set of her USA series "White Collar" with newborn Harper Renn and husband Brady Smith in tow.

As one of the last of the "Beverly Hills, 90210" stars to enter parenthood, Thiessen, 36, makes it official: the "90210" graduates have all grown up. Moving on from the show, which ended in 2000 after 10 seasons, has been another matter.

After The CW Network revived the series in 2008 with "90210," three of the original stars, Shannen Doherty, Jennie Garth and Tori Spelling, signed on for guest appearances. As for the other five, no matter where their personal or professional lives take them, they will always be identified with the popular '90s drama about a group of teens living and attending high school in upscale, star-studded Beverly Hills.

As Luke Perry, who played brooding bad boy Dylan McKay, once put it: "I'm going to be linked with him until I die, but that's actually just fine. I created Dylan McKay. He's mine."

Here's a look at where they are now:
