The 21-year-old son of David Beckham and Victoria Beckham has confirmed that he recently proposed to the 25-year-old Transformers actress. "Two weeks ago I asked my soul mate to marry me and she said yes! I am the luckiest man in the world," Brooklyn wrote on Instagram alongside a gorgeous photo of the couple, taken by sister Harper Beckham, which shows Nicola's diamond ring. "I promise to be the best husband and the best daddy one day." Nicola wrote in a message to Brooklyn on her Instagram. "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 much baby and thank you Harper for this picture." After the duo shared their news, Brooklyn's mom Victoria took to her Instagram to celebrate the couple's engagement. It's been six months since the couple first made their relationship official on social media.
