Lady Gaga's new manager Bobby Campbell is featured in Billboard Magazine's "40 Under 40" list, honoring the music industry's top young players picked by the magazine's editors based on their clients' impact, audience, and chart and touring performance.

"We challenge each other, but we're pretty much in lock step," Bobby said of working with Gaga, who is his only client.

He adds that Gaga's role on the upcoming season of American Horror Story "will show a whole other nonmusical side of her" and as the show airs, "she'll be figuring out the direction of her new record."

Bobby Campbell began working with Lady Gaga in 2009 and is responsible for her most outstanding marketing campaigns, including the release of Born This Way, and the launch of the FAME fragrance. In 2013, he became Gaga's new manager after her split with Troy Carter.
