The 36-year-old star - the son of Ozzy and Sharon Osbourne - popped the question to his girlfriend of two years, Aree Gearhart, over the festive period and she was delighted to accept his proposal.

He wrote on Instagram: "Today I asked the most beautiful and loving woman I’ve ever met to marry me. She said yes!! Life is a series of doors and I’m so excited to walk through this one with her. (sic)"

Jack praised interior designer Aree as a "magical being" and said seeing her be a step-mother to his three children, Pearl, nine, Andy, six, and three-year-old Minnie - who he shares with his ex-wife Lisa Stelly - makes his heart "so full".

He added: "She’s truly a magical being with a heart bigger then anything I could have imagined. Her step-mom skills make my heart so full. I couldn’t be happier then I am right now."

Aree shared the same picture of the couple, which saw her hand, featuring her engagement ring, placed on Jack as he snapped a selfie of them in a wintery setting.

She added the caption: "today my best friend asked me to marry him in a magical winter wonderland. i’ll love you forever and then some @jackosbourne . my soulmate, my adventure partner, my protector. i’m ready for forever w you + our tribe. (sic)"

Jack's sister Kelly Osbourne commented: "I’m so so so beyond happy!!! Now we really are sisters!!!! I love you so much. Welcome to the family!!!! (sic)"

She wrote: "Ozzy and I couldn’t be happier and more proud of our son Jack’s engagement to Aree Gearhart. We are so blessed to have Aree as part of our family and we wish them a lifetime of love, light and happiness."
