Professor Green and Millie Mackintosh have an ''interesting'' sex life.

The 31-year-old rapper has admitted he and his 26-year-old heiress wife do argue but said that kissing and making up is always fun thanks to their adventurous lovemaking.

He told MailOnline: ''We have got into heated arguments in the past, but everyone gets heated at times! And we do kiss and make up ... a lot! We are f**king married!

''We keep each other interested and surprise each other. There have been a lot of pleasant games played.''

And Pro Green - whose real name is Stephen Manderson - insisted that their arguments are minor and they could not be happier, despite rumours to the contrary.

He said: ''Millie and I argue over her not turning the lights off, me leaving my boxers on the floor! Even though it might get heated, it's healthy.

''We spend out whole time taking the mickey out of each other and we love it! It is never mean, it is just a giggle and if it wasn't then I wouldn't be with her! Your looks are going to go but your sense of humour always stays!''

The rapper also joked that fans will have to get used to more racy pictures of them, including a recent picture of the pair in the bath that he posted, as, despite sometimes seeing a therapist together, they have a solid marriage.

He explained: ''We haven't had marriage counselling, all I said is that I see a therapist and Millie now sees one too. We have sat down with her together so she can explain things.

''We are going to have to wait and see if our marriage needs saving. Some people want there to be trouble because it makes it more entertaining, but sorry guys! We are happy and you are going to have to continue seeing pictures of Millie in the bath!''
