These two are so cute.

So last week, the love Romeo Beckham celebrated his 16th birthday. There was cake, there was singing, and there was Elton John. Yep, Sir Elton is Romeo's godfather, so he was on hand to celebrate with the youngster. And while the whole Beckham clan wished Romeo a happy birthday, Brooklyn Beckham went all out. Romeo's big brother, Brooklyn, shared the sweetest snap of the two of them on Instagram. https://www.instagram.com/p/BnLpy53DkVs/?taken-by=brooklynbeckham The picture shows a young Brooklyn holding newborn Romeo. And our hearts exploded. The adorable throwback picture was captioned: "Wow. 16 xx happy birthday Romeo :) love you."
