Couple kiss at Billboard Music Awards 2015

Now, its official!Taylor Swift and Rita Ora's ex beau Calvin Harrisare a couple!

Both further confirmed their romance by sharing a sweet kiss before hundreds of onlookers at the Billboard Music Awards in Las Vegas on Sunday, May 17.

The pair seemed very relaxed in each other's company during the ceremony with the Scottish DJ, tucking one arm behind Taylor.

Both looked quit a catch with Taylor rocking a stunning backless beaded low-cut white jumpsuit by Balmain and the handsome superstar DJ smartly dressed in a fully buttoned up black shirt.

Just for the fact that his ex Rita, whom he dumped via Twitter last year, was also at the event, we wonder how she would feel seeing all of these pictures.
