Selena Gomez had plenty to celebrate on Friday night after kicking off her Revival Tour in Las Vegas.

After a busy night of dancing and belting out her hits, the 23-year-old headed to an after party at Light Nightclub at Mandalay Bay Hotel and Casino.

Selena looked stunning for the red carpet event in a slinky silver gown, which clung to her incredible figure and allowed her to show some skin.

The pop star went bra-less and flashed her cleavage thanks to a plunging neckline, while a thigh-high slit left her slender legs on show.

Selena teamed the daring dress with a pair of fluffy heels, and decided to forgo any other accessories.
