Jessica Simpson is looking for an "artistic man".

The US singer-and-actress - who counts American footballer Tony Romo and womanising singer John Mayer among her ex boyfriends, and used to be married to singer Nick Lachey - said she wants her next husband to be fit into her "emotional type".

She said: "My next husband will be an artistic man. It will show you the colours of my character, the person that I fall in love with next.

"I don't even have a type! I don't have a physical type. I have an emotional type."

Jessica - who was most recently romantically linked to Billy Corgan - also said she would never appear naked in any role, and is saving herself for her next love.

She added: "I will never do nudity. I don't care how dark and intellectual the role could be, you know. I don't care if I could get an Oscar for it, I'm not going to do it.

"Those accolades mean nothing to me. I don't think people deserve to see what's under my clothing. That's only for my next husband ha ha ha!"

The 'Come On Over' singer - who gave up country music in April 2009 after a widely criticised move from her pop roots to the genre in 2007 - also reflected on her upcoming 30th birthday, admitting her life has turned out differently to how she thought when she was young.

She told Allure magazine: "I never really thought, growing up, 'What am I gonna be like when I'm 30?'

"I just kind of thought I had it figured out; I'm going to be this great pop star, have my songs on the radio, be married, and have babies.

"But things can be taken away from you. A song can not be played on the radio. An album can not work."
