Hats off! Delta Goodrem strips to 'You Can Leave Your Hat On' in new ad

Delta Goodrem has indulged us with a striptease to Joe Cocker's 'You Can Leave Your Hat On' in her new ad for Oral-B 3D White. But does she go the Full Monty? Watch above to find out!

The 29-year-old singer flashes that high-wattage smile throughout the 90-second toothpaste commercial... while removing various items of clothes and making a quick dash to the piano.

Note the liberal use of hair-choreography — come on, don't pretend you haven't done a Beyonce-style hair-flip before?

Delta is currently a coach on The Voice Kids, which airs at 6.30pm on Sunday nights on Nine.
