In 2014, "Guardians of the Galaxy" actress Zoe Saldana defended Spears on the controversy involving a raw version of Spears' song "Alien" without auto-tune, which was leaked online.

During her recent appearance on Bravo TV's "Watch What Happens Live," Saldana said, "I'm pretty sure that 80 percent of our musical artists would be mortified if they were caught singing without auto-tune."

Saldana also told the show's host Andy Cohen that she has "a huge amount of respect for Britney Spears."

"I've always said this, and I will always continue to say it. She was the one big, big celebrity that I met, when I started to work in Hollywood, who really was humble," Saldana explained. "Whatever was going on in her mind or in her world, it was never about hating her neighbor."

"Alien" is from Spears' eighth studio album "Britney Jean." When the track leaked, its producer William Orbit said it was not the final take but was just a vocal warm-up, Huffington Post has learned.
