LISTEN: Christina Aguilera Drops 'Twice'

Christina Aguilera shows off her one-of-a-kind vocals on “Twice,” the second single from her comeback album Liberation.

The ballad starts slow and soft, building to a powerful climax.

"Sometimes I wonder what is the meaning of my life / I found the price of love and lost my mind,” Aguilera sings. “I will forgive them all of my wrongs and my rights / I'd do it all again and won't think twice.”

“Twice” follows “Accelerate” ft. Ty Dolla $ign and 2 Chainz.

Liberation, Aguilera’s first album since Lotus in 2012, is set to drop on June 15. She will hit the road on Sept. 25 in support of the collection and make one Canadian stop – at Ontario’s Casino Rama on Oct. 11.

Aguilera also makes a cameo in the new comedy Life of the Party.

The singer is teaming up with Demi Lovato to perform “Fall in Line” on the Billboard Music Awards, which air May 20 on CTV.
