Skepta has got his fans buzzing after revealing he's expecting his first child - six months after it was first reported he was secretly dating Naomi Campbell.

The London grime star, 35, shared a sonogram on his Instagram page on Monday, captioning it simply with a red rose.

Skepta, whose real name is Joseph Junior Adenuga, has always been notoriously private about life behind closed doors, but it's thought he's been secretly dating the supermodel, 48, for months after being introduced by mutual friends.

Back in October the Mercury Prize winner first set tongues wagging when he shared a snap of them cuddling up together on Twitter. He captioned it with a pink heart emoji.

Last year Naomi gave a rare interview where she spoke about her desire to have children if the right man came along.

The supermodel previously said she had considered adoption, but admitted she was now thinking about having her own biological child.
