U2 rocker Bono admits he's irritating.

He explained, "I know I can be a pain in the a**. I have an annoying gene; it's in my DNA - I even annoy myself. When righteous anger turns to self-righteous, projectile vomit is the right response."

The rocker recently landed in fourth place on a list of "Best Celebrity Role Models." He was beaten by Angelina Jolie, George Clooney, and Miley Cyrus. Miley? Ouch, that's gotta hurt.

Meanwhile, former U.K. prime minister Tony Blair is convinced Bono could be running the world if he hadn't shunned politics for a career in rock music.

In his new autobiography"A Journey" Blair writes, "(Bono) could have been a president or prime minister standing on his head. He had an absolutely natural gift for politicking, was great with people, very smart and an inspirational speaker... motivated by an abundant desire to keep on improving, never really content or relaxed."
