David Beckham finally joined Instagram today (May 2), and he's already shared multiple photos.

The former footballer posted a black and white photo of himself topless in bed as his debut on the photo sharing site, captioning the image: "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".

Today is Beckham's 40th birthday, and he will celebrate with a bash at a six-star resort just outside Marrakech in Morocco.

His wife Victoria also shared a few snaps from her husband's big day, posting a photo of themselves outside a private plane and one of her hugging him while wearing a bikini.
