The 30-year-old rapper - who is married to the former 'Made in Chelsea' star - has revealed they do not want to have a baby yet because their dogs are so demanding.
He said: ''Our dogs are our b****y children at the moment. Looking after two dogs, one of whom is a pup, is a chore. But yeah I wouldn't swap them for the world.''
The couple got married in 2013 but are keen to make sure their personal situations are more sturdy before welcoming a child into the world.
The 'Read All About It' musician - whose real name is Stephen Manderson - said: ''Kids? Not yet, we've got a lot more work I think.''
Professor Green released his third studio album 'Growing Up In Public' in September, while his 25-year-old lover recently launched her own clothing line, meaning their schedules are too packed to start a family.
He added to OK! magazine: ''We're both so busy in our careers it's definitely not the right time to have children yet. It is on the agenda but I think we both want to be a bit more secure before we do it, and then take the dive into the unknown.''
