After Lauren Conrad's exciting news that she's teaming up with MTV again to celebrate the 10th anniversary of The Hills, we've taken a look at what the rest of the gang are up to these days...
Lauren Conrad
Since The Hills, LC has released nine books, ventured into fashion and launched her own beauty products. She married William Tell on 13 September 2014 in California.
Heidi Montag
Speidi is still going strong! The twosome have capitalised on their relationship, appearing on further reality TV shows together and spend a lot of time talking negatively about The Hills and Lauren.
Audrina Partridge
Audrina continued on the reality TV path for a while, but these days it's all about family. She and Corey Bohan got engaged in November last year, and a month later it was revealed they are expecting their first child – a baby girl.
Whitney Port
Like Lauren, Whitney has focused mainly on fashion since The Hills. She released a book, joined the judging panel for the eighth series of Britain and Ireland's Next Top Model – and she also married The City producer Tim Rosenman in 2015.
Kristin Cavallari
Kristen managed to land a few acting parts, but her biggest job since the show has been becoming mum to her three children. She and husband Jay Cutler are parents to sons Camden and Jaxon and daughter Saylor.
Lo Bosworth
Lo now runs a Revelry House, a brand "designed to serve the modern hostess". In 2013 she started attending The International Culinary Centre in New York City, where she studied Farm to Table Cuisine.
Stephanie Pratt
Spencer's little sister headed for the UK when The Hills finished – and ended up starring on Made in Chelsea! She had a brief romance with Spencer Matthews, and released a book last year in which she wrote about her teenage drug problems.
Brody Jenner
These days Brody is better known as the son of Caitlyn Jenner, and step-brother to Kourtney, Kim and Khloe Kardashian. He met blogger Kaitlynn Carter in 2014, and earlier this year they confirmed their engagement.
