Sharon Osbourne is very much the proud grandmother and took to social media on Tuesday to share her latest snap of the baby boy.
Mrs O, 70, posted a sweet image of the youngster on her Instagram account and fans couldn't help but notice the hilarious reference to her husband Ozzy in the photo.
Labelling baby Sidney "Little O", Sharon uploaded the shot of the tot looking adorable and snug in a bat-themed swaddle blanket.
