Justin Bieber has a new app on his Facebook page that lets anybody “kiss” the teen pop sensation. It is not known, however, if Justin Bieber's “baby mama” Mariah Yeater has used the Facebook app.

When fans log onto the Facebook page, they see a picture of a female silhouette “kissing” Bieber. With the use of a webcam, the user simply clicks on the “webcam” icon, allowing the app access to the camera. The user then poses sideways in a kissing position.

The app then automatically puts the user’s picture next to Bieber's.

After the picture is taken, it can shared on Facebook and tweeted to friends. It can also go into a photo gallery with thousands of other Bieber-kissers from around the world. People can also “like” your photo.

Bieber is currently in London promoting his new Christmas album, “Under the Mistletoe,” which is currently at the top of the Billboard charts. He was recently seen riding one of London's famous double decker buses and tweeted a picture of himself on the bus and enjoying the view from atop.

Despite being accused of fathering a child as a result of a one-night stand with a fan in a bathroom while being known to have a family-friendly reputation, Bieber, a self-professed Christian, still flirted with the hundreds of young female fans on hand to get a glimpse of the superstar at one of the ceremonies he hosted in London.
