As well as preparing for his forthcoming birthday party in Marrakech, the retired footballer decided to give his fans a little present of their own...
And we're very grateful he did!
The national treasure joined picture-sharing website Instagram and posted a beautiful black and white selfie - from his bed! - with a sweet message to his ever loyal supporters.
He wrote: "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."
Fans were quick to wish the sporting star a happy birthday, with one gushing: "Happy birthday to the hottest 40 year old."
And, yes, we have to agree - David looks mighty fine!
Proud wife Victoria also took to social media to wish her hubby a happy day and to share a picture of their arrival in Morocco.
Alongside a snap of them beside a private jet, Victoria wrote: "So excited to be celebrating David's birthday x #DB40x vb."
Chef and Beckham friend Gordon Ramsey and his wife Tana have already been spotted arriving at the airport to join in the festivities.
David is thought to be holding his bash at the Amanjena resort, where he and wife Victoria Beckham renewed their wedding vows in 2008.
Happy birthday David!
