Lauren Conrad and Heidi Montag will always be linked by The Hills.

Even a full season after LC retired from the show she made famous, and years after she and Heidi stopped being close, she's still asked about her.

LC was reluctant to comment on the recent Heidi Montag plastic surgery debacle this morning on Good Morning America, but did so diplomatically.

Asked what her reaction was after seeing Heidi's new appearance, which some liken to that of a circus freak, Conrad paused and said, "It's a look."

That it is. And that's as nicely as one can put it. Well done, LC!

Lauren Conrad won't criticize her former BFF, but says surgery isn't for her.

Conrad, who just celebrated her 24th birthday Monday, said despite the pressures on young women in Hollywood, she won't be going under the knife.

Asked if she'd had or considered plastic surgery, the best-selling author and fashion designer laughed and said "not so far, no... it's a personal choice."

"Everybody's different. Everybody needs to do what's good for them."

Lauren Conrad left The Hills after five seasons and is now focusing on her fashion line at Kohl's, plus her work as an author of young adult fiction books.

Montag is focusing on undergoing plastic surgery pretty much constantly and coming out with some of the worst music in human history. Team Lauren!
