The rest is NOT still unwritten!

Lauren Conrad sat down with MTV to mark the ten year anniversary of The Hills with a new That Was Then, This Is Now special, and the reality star dished on all those famous makeups, breakups, fights, and drama.

Among her bombshells?

LC threw a fair amount of shade by revealing that she didn't think she would be friends with her fellow castmates had they not all been cast on the same show. Ouch!

The Paper Crown designer also went into more detail about her painful on-camera breakup with boyfriend Jason Whaler. "After we went on a break from filming, it was like a couple weeks in, I finally decided to end things. We broke up. I said you have three days to get your stuff out, I'm having the locks changed on Monday. So when I saw Jason that day, it was the first time I had seen him since we had broken up. It was really hard. What made it harder was I could see he wasn't sober," she revealed.

"That really broke me, because I felt like a responsibility to take care of him, and I felt like when we broke up I was abandoning him. Because there were a lot of nights that I was getting 2 a.m. phone calls and I had to go pick him up passed out in the back of a club. So I was like who is doing that now, I know he doesn't have friends who are doing it...I was like, oh god, no one is taking care of him," she added.

Since the show, Conrad built a fashion and lifestyle empire and married husband William Tell, Jason Whaler got sober and opened a recovery center, Audrina Patridge got engaged to fiancé Corey Bohan and had a baby, Kristen Cavallari had three kids with NFL quarterback husband Jay Cutler, and Spencer and Heidi went broke!
