Carly Rae Jepsen performed a mashup of 'This Kiss' and 'Call Me Maybe' at the 2012 American Music Awards tonight (Nov. 18).

We intuited that CRJ would sing 'Call Me Maybe,' not just because it's her biggest hit and a defining song of 2012, but because she descended to the stage in a pink, French-style telephone booth to sing her new single 'This Kiss.' With three phone booths as stage props, it seemed like a foregone conclusion that she would sneak in a little 'Call Me Maybe.' How could she not?

For the first half of the performance, which was 'This Kiss,' there were Warholian lips of all different shapes, sizes, colors and designs flashing on split screens behind her and her backup dancers.

Jepsen was utterly adobs in a short white dress paired with a white blazer, black booties and pearls. She was bubbly and cute.

But being the crowd pleaser that she is, she ended up splitting 'This Kiss' with 'Call Me Maybe,' so it was a mashup of her new single with her hit that was perhaps the biggest song of the summer of 2012.

She engaged the crowd to sing along with her, which they did. R&B star Brandy and actress Ginnifer Goodwin were dancing in their seats! And CRJ's frothy, fizzy, confectionary style and her sweet smile also had us grooving on our couches at home.
