Feliz Cumpleanos! Tiffani Thiessen looks youthful as she rings in her 40th birthday with a festive party in Mexico

It might be 21 years since Tiffani Thiessen first played a high school cheerleader on Saved By The Bell, but the glamorous actress could clearly pick up her pom poms once again.

Looking trim and youthful, the beauty glowed as she rang in her 40th birthday in Playa La Ropa, Guerrero, Mexico on Saturday.

By her side was her husband Brady Smith and about a dozen friends.

Matching the picture perfect location, the Beverly Hills, 90210 alum looked vibrant in bright hues as she partied barefoot on the beach at the Viceroy Zihuantanejo.

Her mini dress was full of blue, pink and orange flowers.

Even the White Collar actress' makeup was full of color with bright pink lipstick and soft pink eyeshadow. Tanned legs, no doubt achieved by more than a few hours soaking up the Mexican sun by the pool, added a fresh vacation look.

According to E! News, the night was made more special as the group watched a 15-minute video with taped messages from family, friends and past costars including Lindsay Price, Ian Ziering, Mark Paul Gosselaar and Elizabeth Berkley.

Another friend gave the star a large tank that, as a joke, bore the words 'I'm bringing the Amber back,' which referred to when the star used to go by the full stage name Tiffani Amber Thiessen.
