Brooklyn Beckham and Nicola Peltz are engaged!

Brooklyn Beckham and Nicola Peltz shared on Instagram on Saturday that they're getting married!

They both posted the same photo of the photographer holding the actor, who was wearing a stunning yellow dress, with rings of their fingers.

"Two weeks ago I asked my soulmate to marry me and she said yes xx I am the luckiest man in the world. I promise to be the best husband and the best daddy one day. I love you baby xx," the 21-year-old wrote.

The Bates Motel star commented: "I'm so lucky to call you mine" and wrote on a post of her own: "You've made me the luckiest girl in the world. I can't wait to spend the rest of my life by your side. Your love is the most precious gift. I love you so so much baby."

Brooklyn's mom, former Spice Girl and fashion designer Victoria Beckham shared her congratulations as well, writing on Instagram that this is "the MOST exciting news".

"We could not be happier," she said. "Wishing you so much love and a lifetime of happiness. We all love you both so much x."

The couple were first spotted together in November at a Halloween party. By then they were spending lots of time together, sources said, with Brooklyn having already met the 25-year-old's family.

Congratulations to the happy couple!
