'Extra' Exclusive! Justin Bieber on Batmobile, Pet Adoption and Holiday Album

Pop sensation Justin Bieber sat down with "Extra's" Maria Menounos to shed some light on those photos of him standing next to his Batmobile. The Biebs explained, "Those pictures weren't from me getting pulled over."

The teen star, who has a custom-made Cadillac resembling the Batmobile, was reportedly pulled over last week after cutting off a CHP officer, but was let go with just a warning. Bieber said he decided to go with the Batman theme because "I liked the idea. I just wanted it to be a Batmobile. It looked like it, so I put on the symbols and everything."

The 17-year-old also set the record straight on adopting a dog, saying, "No, it's false," adding that he has no idea how the gossip gets started. "I dunno, people make stuff up."

Justin Bieber: Up Close and Personal

Although it's only Halloween, Justin is already getting into the holiday spirit with his Christmas album, "Under the Mistletoe." One of the songs featured on the album is Mariah Carey's tune, "All I Want for Christmas Is You." Bieber, who chose to sing the song in the same pitch as Mariah, said, "I wasn't going to change her song because it's a classic, so I had to sing it really high."

Bieber was also up for a little ping-pong challenge with Menounos, but before taking the paddle, had a special message for his fans. "My Christmas album is coming out... it's called 'Under the Mistletoe,' make sure to get it tomorrow [Nov. 1]."
