Fearne revealed her exciting news on Twitter last night (12 December) after Jesse popped the question on Sunday.
In February, the couple welcomed their first baby into the world - a son called Rex - so their engagement is a perfect way to top off the year.
Fearne, who stars on Celebrity Juice and who has her own Radio 1 show, gushed: "I'm over the moon to tell you that on Sunday Jesse proposed and I happened to say yes."
She finished her tweet with a cute red heart symbol.

Fearne first started dating Jesse - who is the son of Rolling Stone Ronnie Wood - in 2011.
In a recent interview with Cosmopolitan, Fearne revealed that marriage was on the cards for them both.
"I'd love to get married and I'm sure Jesse would too, but we don't have any plans yet," she admitted.
Well you can certainly start planning now.
