On Saturday, Beckham rang in his birthday, shirtless, on Instagram. He shared a shot of him in bed and captioned the photo: "Good morning and hello! It's great to finally be on Instagram, been a long time coming but I can't wait to start sharing all my special moments with you. Thank you for all your birthday messages so far. Looking forward to a great day with friends and family x."

As the sun appeared to set behind them, Beckham shared a snap of him and his wife as she lied gently on his chest and they smiled into the camera.
