"Two weeks ago I asked my soul mate to marry me and she said yes. I am the luckiest man in the world. I promise to be the best husband and daddy one day. I love you baby," Brooklyn wrote.

According to a source: "Brooklyn has been telling his friends in LA that he and Nicola are engaged. It's common knowledge among their group of friends. They are smitten."

Meanwhile, the source added: "David and Victoria have very much given this relationship their blessing. It's a very exciting time for the whole family and after a few previous rocky relationships, they think Brooklyn has landed on his feet."

Last summer, Brooklyn had split from model Hana Cross.
