Ten years after its premiere, The Hills is finally lifting the veil on it all.

And who better to walk us through the big reveal than Lauren Conrad? The show’s heroine is returning to the network that launched her career with the highly anticipated anniversary special, The Hills: That Was Then, This Is Now.

“So often we would say if you knew the real story, you would understand,” says Conrad, 30, in the promo clip. “And what I’d like to do is tell that story.”

The show will take a look at what things are like now, “and then we’re going to take a look back at this show and reveal things that we haven’t talked about before,” Conrad promises.

Check out a few sneak peeks from the special below.

In one preview that will be extra-sentimental for fans, Conrad recreates the iconic intro to the show, signature dark sunglasses and all – only this time, she’s driving a Porsche, not a BMW, and Natasha Bedingfield‘s classic theme song, “Unwritten,” gets switched up a bit too.

“Everyone talks about the soundtrack to their lives. Ten years ago, this was the soundtrack to my life,” says Conrad, before reaching down and changing the track.

“That was then, this is now,” she says as the new tune starts playing. “I cannot believe it’s been 10 years since we made The Hills.”

Another preview clip features Conrad reflecting back on the highs and lows (and there were certainly a lot of lows) that the show captured over the years.

“The show isn’t something that I like to relive,” Conrad admits as clips of her infamous "You know what you did" blowout with Heidi Montag (now Pratt) unfold, spliced with drama with Conrad’s ex-boyfriend Jason Wahler.

“I don’t go back and watch the show,” Conrad admits. “Everybody’s different, but for me it doesn’t exactly bring back the best of memories.”

And even Conrad’s parents make an appearance in a final sneak peek at the special.

“She kind of went off on her own pretty young,” dad Jim says. “You know, her early 20s. She said, ‘You know what Dad, I’ve kind of got this.’ ”

As for watching her on TV over the years? They liked it!

“She handled herself beautifully,” says mom Kathy. “What’s not to like?”

“The thing is, there were very few things that happened on the show that we didn’t know about,” Jim explains.

“Hot tip! If you’re going to be on reality television, tell your parents stuff, since they’re going to find out,” adds their daughter with a laugh.

The Hills: That Was Then, This Is Now airs Tuesday at 9 p.m. ET on MTV.
