"@LaurenConrad Congratulations on your engagement!!! So happy you found true love! I pray you have a long, happy, blessed marriage!" Heidi tweeted.
Spencer added: "@LaurenConrad Sincerely wishing you all the happiness in the world on your engagement. Congratulations!"

"I am very excited to share with you guys that William and I got engaged over the weekend. I am beyond thrilled!" she wrote.
