Yesterday (13 October), Lauren told fans that William had proposed with a diamond ring, sharing a picture of the sparkler online.
Following her exciting news, former BFF Heidi Montag took to Twitter congratulating Lauren - and now her husband has also sent some kind words to the reality star-turned-fashion designer.
Throughout The Hills, the pair were arch enemies and their dislike of each other drove Lauren and Heidi apart, so we're surprised to see he has got in touch!
@LaurenConrad Sincerely wishing you all the happiness in the world on your engagement. Congratulations!— Spencer Pratt (@spencerpratt) October 13, 2013
But Spencer tweeted: "@LaurenConrad Sincerely wishing you all the happiness in the world on your engagement. Congratulations!"
Needless to say, Lauren has not replied to Spencer. Or Heidi for that matter...
