Obama mash-up video goes viral

BarackDubs strikes again! The viral video series that mashes up President Barack Obama's speeches set to popular songs has a buzzy new release. In it, the commander in chief "sings" "Call Me Maybe" by Carly Rae Jepsen.

The Canadian pop star's song, which was released last September,  has been getting a lot of attention lately. During Sunday night's Miss USA pageant, the contestants did a lip dub of the song that aired during the show. It also featured pageant owner Donald Trump singing as well as co-hosts Andy Cohen and Giuliana Rancic.

Other celebrities have taken notice of Jepsen's pop hit as well. Justin Bieber and Selena Gomez helped make "Call Me Maybe" a hit by rounding up some of their VIP pals to record a video of themselves lip syncing to the song. The song became a megahit and Jepsen, who is signed to the same label as Bieber, landed a gig opening for him on his tour.
