Ah, they grow up so fast.

First, he's taking part in some spread for 'Hello!' magazine as a baby, the next minute he's getting engaged to somebody who was in 'Transformers: Age of Extinction'.

Sunrise, sunset. Anyway, David and Victoria Beckham's eldest, Brooklyn Beckham, is now engaged to American actor Nicola Peltz. Brooklyn, 21, asked the actor - who is four years old than him - and she obviously said yes. On top of that, both David and Victoria gave their blessing to the union.

If you think 21 is a young age and it's all a little bit impulsive, the pair have been dating since January. So, yeah. Brooklyn took to Instagram and declared that, "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."

Well, isn't that nice.

Well-wishers in the comments included Formula 1 driver Lewis Hamilton, Eva Longoria, 'Stranger Things' alum Millie Bobby Brown, comedian Jack Whitehall, and the fast-fashion brand Pretty Little Thing.

N'aww, so cute.
