"Laguna Beach" Cast -- Then & Now

"Laguna Beach" is back on the air -- and the show's original cast members have been very busy since leaving the show in 2006.

This summer, MTV is re-airing the first two seasons of the popular reality show from 8am-noon every weekday as part of their "RetroMTV Brunch." 

And people are definitely excited.

The show was trending all morning on Twitter -- with many wondering what happened to their favorite OC kids after they were replaced in Season Three.

And while Lauren Conrad, Kristin Cavallari, Stephen Colletti and Heidi Montag have all been in and out of the public eye recently, where are show regulars like Talan Torriero, Jason Wahler and Alex M. now?

Check out the gallery above to find out who got married, who got arrested, who is currently working as a physical trainer and who is now a famous cupcake chef!

Yep, we said cupcake chef.
