SINGAPORE - Pop diva Ariana Grande's first outing in Singapore was an impressive showing of both her flawless vocal chops and her ability to dance in potentially ankle-breaking sky-high heels.

The 24-year-old played to a crowd of over 50,000 at the Padang Stage on Saturday (Sept 16) night for the 2017 Formula One Singapore Airlines Singapore Grand Prix.

The short, one-hour set showcased the best of Grande and her four-octave soprano.

She never broke a sweat, despite the sultry Singapore weather and even managed to hold a tune while cycling on an exercise bicycle on the Nicki Minaj collaboration, Side To Side.

Her catalogue of pop R&B tunes like One Last Time and Bang Bang worked for the diverse crowd, especially the "cat ear"-wearing tweens. Backed by a full band, a small string section and a troupe of male dancers, there was plenty of spectacle to enthrall her fans.

But it was not just the hardcore Arianators who were blown away by her impressive runs and breathy declarations of "Singapore, let me hear you".

Bookending her set with Be Alright and Dangerous Woman, she reeled in the audience with sexy over-the shoulder glances and hair flips aplenty.
