Kym Johnson debuted a new accessory on the red carpet Sunday, and it was courtesy of fiancé Robert Herjavec!

The Dancing With the Stars pro showed off her engagement ring at the Elton John AIDS Foundation Oscars viewing party — and it’s huge! The couple, who met on the reality dancing competition last year, announced their engagement just one day before Hollywood’s big night.

Kym also shared the exciting news with fans on Instagram, captioning a photo of the duo, “I never thought a year ago I’d meet someone who would change my life completely! I’m the luckiest girl in the world because last night the love of my life @robert_herjavec asked me to marry him and I said yes!”

This will be the first marriage for Kym and the second for Robert, who filed for divorce from his wife of 15 years last April.

Congrats to the happy couple!
