The 36-year-old singer knows he can always turn to spouse Crystal Renay for support and advice and loves her "drive and ambition" - as well as her bottom.
Asked who his best friend is, he said: "My wife Crystal. She's the one person on the planet I can talk to about anything and everything. She's the person I know will never judge me ...
"I am a sucker for a woman with some drive and ambition. Confidence is the sexiest thing in the world to me. I don't discriminate in regards to race, colour or creed, but I'm a booty guy."
The 'So Sick' hitmaker - who has kids Madilyn, five, and four-year-old son Mason with ex-girlfriend Monyetta Shaw and son SJ, seven months, with Crystal - also admitted one of his most extravagant purchases came on Father's Day, when he bought a luxury car for himself.
He said: "One Father's Day, I went out and bought myself an SLS Mercedes-Benz, the one with doors that come up like wings. It's honestly the most expensive thing, next to my home of course, that I have purchased."
The 37-year-old singer prides himself on being a "gentleman", but admits it makes people mistakenly think he's a "pushover".
He told Grazia magazine: "I think a lot of people think I'm a pushover because I'm a real gentleman. That's not drue, don't get it twisted."
