Here's a flash from the past that'll bring you right back to 2006, as Lauren Conrad has announced she is engaged to William Tell.

Whoa indeed. The 27-year-old former reality TV star is 'beyond thrilled' after the 33-year-old rocker turned law student proposed to her over the weekend, and Lauren decided to share the news on her blog (which is so very 2006 and Hills-esque) on Sunday saying: 'I am very excited to share with you guys that William and I got engaged over the weekend. I am beyond thrilled! Get ready for lots more wedding content here on as we begin the planning process.'

LC also shared a picture of her classic diamond engagement ring, and later added: 'William and I are overwhelmed by all of your warm wishes. Thank you so much for sharing in this special moment.'

Lauren recently revealed she and William, who have been together for 21 months, are perfect for each other because they have so much in common.

She said: ''He is very good for me because we have a lot in common as far as where we grew up. It's the first time I'm with someone and I'm not explaining things. He also has experience in the entertainment industry, so he understands a lot of things that people don't always get.'

News of her engagement comes just one day after her ex-boyfriend and 'Laguna Beach' co-star Jason Wahler married his fiancee, Ashley Slack, in Malibu, California, on Saturday.
