"This smile is because of Carly Rae Jepsen," Selena tweeted with a photo of Justin showing his pearly whites behind the wheel of an Audi. "We have not stopped listening your song girl!"
"Can't describe how flattered I am," the Canadian singer-songwriter replied. "Thank you @selenagomez and @justinbieber for the love. Xo."
To save you some Googling time, Carly is from Mission, British Columbia, and placed third on the fifth season of 'Canadian Idol.' She released her debut album, 'Tug of War,' in 2008, and has since been nominated for two Juno awards.
Carly is set to release her sophomore album, 'Curiosity,' this year, and recently unveiled her latest single, 'Call Me Maybe,' which is the tune JB and Sel were referring to. Check it out below and let us know what you think of it in the comments.
