Here&39;s British late-night television talk show host James Corden with his amazing singing voice once again, this time with the mysterious Sia.

Watch how they both shine bright like diamonds and swing from the chandeliers, in the car!

The Australian singer songwriter discusses aliens and drugs with James while he sports her hairdo, and then balances 12 eggs on her hands.

Clearly, this titanium duo are bulletproof!
