Stephen Colletti

For three brief, wonderful seasons, viewers were immersed in the lives of the teenage stars of Laguna Beach.

That was over a decade ago, but the cultural impact of that ahead-of-its-time reality series cannot be measured.

STEEEE-PHENNNN!

Stephen Colletti, Lauren Conrad and her husband William Tell partied together last weekend, making for a Laguna Beach reunion ... at the Laguna Beach High School reunion!

Laguna Beach premiered 10 years ago Sunday, September 28, introducing us to the world of Lauren Conrad, Stephen Colletti, Kristin Cavallari and company.

The TV world was never the same, and we're not even being facetious.

Except for The Amazing Race, which wins Emmys for a reason (because it's a great show), reality TV is a lot of mindless entertainment that we watch for very few discernible reasons.

Aside from living in exotic locales and the likelihood of making out with hot guys and girls, what other reason do people have for starring on reality TV shows? 

Lauren Conrad's ex-boyfriend, Stephen Colletti, is dating Chelsea Kane, the Disney and Dancing with the Stars cutie, according to new reports.

"We were set up on a blind date by my manager," Kane says.

Should Milo Ventimiglia worry?

Probably not. But it's been a long time since we've seen Hayden Panettiere mingle with her ex, Laguna Beach alum Stephen Colletti - as they did below at the BlackBerry Bold launch in Beverly Hills Thursday - who she once dated for over a year.

He recently came back to The Hills... but is he back in his former flame's love life? That's the question of the hour re: Stephen Colletti.

The woman in question, of course, is Lauren Conrad.

If The Hills were a soap opera (which it sort of is), this would be the week that the original cast member returned to fireworks and high drama.

Our subject is none other than Stephen Colletti, Lauren Conrad's best friend, then love interest, then... who knows! Anyway, he's alive - and HOT!

From Jason Wahler to Brody Jenner and even brief flings like Gavin Beasley, Lauren Conrad has dated her fair share of guys.

So who does her friend from back in the Laguna Beach days, and her BFF slash roommate now - Lauren "Lo" Bosworth - prefer for LC?

We apologize for missing Stephen Colletti in our celebrity birthday post earlier today. The Laguna Beach product turned 22 on February 13!

Stephen, who famously two-timed Lauren Conrad and Kristin Cavallari - how we would love to have been in his shoes - also dated Hayden Panettiere.

Welcome back, entertainment news and celebrity gossip fans around the world, to The Hollywood Gossip Caption Contest, our Friday afternoon tradition.
