Seeing as they’re arch rivals, absolutely nothing at all you’d guess. But you’d be wrong, as it seems the girls share the same taste in underwear - namely, the collection from American brand Spreegirl.

Heidi was first to wear the label, sporting a pair of their frilly knickers on the cover of Rolling Stone that she and her fellow Hills stars graced back at the start of May. Then, just two short weeks later, Lauren was snapped backstage at an event selecting her favourite pair of cute boy shorts along with Lo and Spencer’s sister Stephanie.

The Hills star Audrina Patridge collects her clothes from the dry cleaners in Beverly Hills on Wednesday.

Audrina recently talked about her diet as well as a little “exercise advice,” in the latest issue of TV Guide Back in high school, The Hills castmate had to guzzle milk to slow her metabolism. Now that it’s under control, the 23-year-old swears by portion control: “I order what I want when I’m out, but I don’t eat all of it.”

Patridge works up a sweat five hours a week, doing laps in her backyard pool or hiking in Runyon Canyon or just hanging at home. ”When I’m sitting in front of the TV, I lift five-pound weights or do squats,” she says. “And I wear heels when I vacuum because it works my calves and my butt.”

Lauren Conrad and current BFF Lauren Bosworth leave Crown nightclub in Hollywood on Wednesday.

The pair also stopped at CocoDeVille and other night clubs for their mid-week partying. Socialite Nicky Hilton was also on-hand for the festivities.

The 22-year-old actress was recently interviewed by Glamour magazine’s editor Petra Guglielmetti who described Lauren as, “Seemingly really sweet/almost a little shy. I wasn’t getting stuck-up vibes. When I needed to find the ladies’ room, she walked me there, despite 10 publicists who could have done so instead.”

Lauren Conrad does a little pre-holiday shopping at Barney’s New York in Beverly Hills on Thursday.

The 22-year-old actress/fashion designer was interviewed by Petra Guglielmetti of Glamour magazine who said she was, “Shockingly well-spoken considering the inane dialogue we generally see her involved in on ‘The Hills.’ Recited tons of stats from memory when describing the new m.powerment initiative.”

Lauren discussed her new fashion collection for Mark and their initiatives that donate proceeds from certain accessories from which go to charities which help to prevent violence against women.

Heidi Montag and Spencer Pratt show some PDA (surprise!) at the DMV in Santa Monica, Calif. on Tuesday as they register to vote for the upcoming presidential election.

Spencer was seen wearing a “Jesus Loves THIS Guy” t-shirt. And in case you missed it, YES, Heidi DID compare herself to Jesus Christ. She also would like to release a Christian album and become a missionary to Africa! What will she come up with next?
