I went a little nuts: Adam Levine on his rockstar lifestyle

Los Angeles: Maroon 5 frontman Adam Levine admits that early fame got into his head.The 35-year-old singer, who is set to marry supermodel Behati Prinsloo, says he is not an easy guy for people to like but he has evolved over the years, reported a magazine.

"Would it be really easy to assume that I was a douchebag? Definitely. One hundred percent. I`m not an easy guy to root for," he says in an interview. The `Voice` coach, 35, poked fun at his rock star image which include his multiple relationships. "Men are not as sophisticated as women. They`re not as mature as women. They`re not as connected with their emotions as women. There`s a very Neanderthal quality that still exists in a lot of men," the Begin Again star said. "There was a time in my life when I lived probably a bit more on the primal level. And it was amazing. All of a sudden I had money in my bank account. I hadn`t had a break in a long time. And I went a little... Nuts. I deserved to go a little bit nuts. And I had the time of my life." Levine, however, now want people to believe that he is a changed guy. "People change, people grow up, get more self-aware... If I knew everyone in the world, they would love me. Every one of them. I`m not arrogant. I`m cocky. It`s different. Cocky is playful."
