"They make me a trending topic on Twitter every day," Bieber marveled. "It's pretty incredible. My fans have made me a trending topic every day. I don't think there's been a day in the past month that I haven't. So it's pretty incredible."
The singer — who is still one of the most devout celeb users of the social-networking site — said he loved using the site to stay connected to his fans. "I love Twitter," Bieber said. "I use it for being able to interact with my fans as well as promote stuff."

"They're like, 'I never thought you were gonna respond!' " he added. "And I say, 'You thought wrong.' "
