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:

In turn, Priestley quickly became a teen idol. When he left the show after nine seasons, he struggled to be taken seriously as an actor, joining the casts of "Tru Calling," "Love Monkey" and "Side Order of Life."
Priestley may have been happier working behind the camera, where he directed 19 "Beverly Hills, 90210" episodes and served as executive producer until the show's cancellation. He has also directed episodes of "7th Heaven," "The Secret Life of the American Teenager," and Spelling's return to the new "90210."
Spelling has said many of the original cast members were sleeping together during the show's run, and Priestley admitted to Howard Stern that he and co-star Doherty, who played his twin sister, had indeed during the first season.
Following his divorce from actress Ashlee Petersen, whom he met on the set of "Beverly Hills, 90210," Priestley, now 40, married make-up artist Naomi Lowde, with whom he has two children. A devotee of race car driving, Priestly survived a 2002 crash during a practice run. He has provided commentary for IndyCar racing and recently became a joint owner of his own Indy team.
