First Lauren Conrad announces her engagement and now her former co-star Holly Montag has confirmed she is also set to walk down the aisle.

It was her sister Heidi who broke the news. She tweeted yesterday: “A HUGE congratulations to my amazing loving sister on her engagement to Richie! Answered payers! love u so much & am so ecstatic for u! [sic]”.

Holly, who is the low-key one in the family, followed the announcement up with a snap of her and her beau Richie as well as the ring.

Holly was also one of the stars of MTV reality show The Hills.
