R&B singer Mary J. Blige has slammed rumours she is pregnant by her music executive husband Kendu Isaacs.

Online reports suggested the Family Affair hitmaker was expecting her first child, following speculation earlier this year that she was considering adoption.

But the star has dismissed the rumours she's expecting, insisting there isn't a "slight" bit of truth in them, according to GossipCop.com.

In September Blige said she would be a "poor parent" because she is far too busy to adopt any kids, and is happy looking after Isaacs' three children from a previous relationship.
