Sia will sing 'Finding Dory' theme song 'Unforgettable'

Ellen DeGeneres rolled out another piece of Finding Dory news on Friday.

Sia will provide the music for the Finding Nemo sequel's closing credits. Fittingly, for a movie about a forgetful fish, it will be a cover of Nat King Cole's Unforgettable.

"When I asked our next guest to sing the theme song to Finding Dory, I was thrilled that she said yes," DeGeneres said before introducing Sia, who was on hand to perform her version.

"Dory's story makes me teary," the Australian singer/songwriter confessed.

Paste BN has previously reported that Dory's parents will be voiced by Eugene Levy and Diane Keaton. Dominic West and Idris Elba will play a pair of gangster sea lions.

Finding Dory arrives in theaters June 17.

Meanwhile, Sia announced earlier this week that she's embarking on her first tour in five years with opening artist Miguel. It kicks off Sept. 29 in Seattle.
