"I am beyond thrilled! Get ready for lots more wedding content here on LaurenConrad.com as we begin the planning process."

She later added: "William and I are overwhelmed by all of your warm wishes. Thank you so much for sharing in this special moment."

The 27-year old reality TV star also posted a snap of her diamond sparkler along with the blog post.

Last year, reports suggested that Conrad was 'hoping to marry' her law student beau, with a source telling Us Weekly: "They really connected. She hopes he's 'the one'!"

Congratulations!
