Justin Bieber recently dished on why there has been so much PDA between himself and girlfriend Selena Gomez.

She has very kissable cheeks, Bieber told Ellen DeGeneres on her talk show, airing Tuesday.

I feel like I only live once, it sucks to always have to hide it . . . I just do me, he added.

You should do you, you're a good person to do, DeGeneres joked.

Bieber is currently in the middle of a slew of television appearances in support of his new album, Under the Mistletoe, out Tuesday.

The 15-track Christmas album features duets with Usher, Mariah Carey, Boyz II Men and others.

On Monday, Bieber also made a stop at The Tonight Show with Jay Leno, where the singer debuted a new hairstyle and was greeted by a sea of screaming fans.

Gone are the luscious, sweeping locks that have become a trademark look for Bieber.

Now, the young entertainer has a spikey hair look that has naturally caused a Twitter frenzy.

Justin Bieber has new hair. That is all, wrote one user.

Bieber's new hair has also inspired People.com to launch a What's His Best Hair? poll.

On Leno, Bieber brought sushi to share with the talk show host, talked about his customized Batmobile Cadillac and revealed details of his one and only speeding ticket.

I was speeding . . . I wasn't going too fast, but thing was, it was in a construction zone, and I didn't realize it, Bieber explained.

He pulls me over . . . and I was like, 'Why, do you like my car?' That was the wrong answer, he added.

Bieber recently wrapped a 16-month world tour, which brought him to places like Australia, Malaysia, Japan and most recently, Venezuela and Brazil. The tour has grossed an estimated $55 million in ticket sales alone.

Also on Monday, Bieber became the first person in YouTube history to reach two billion views on his channel. Lady Gaga achieved the one billion views mark about one year ago.
