Actress Zoe Saldana has praised singer Britney Spears' humble attitude.

The "Avatar" actress, who worked with Spears in the 2002 release "Crossroads", has a "huge amount of respect" for the latter, reports contactmusic.com.

"She was the one big, big celebrity that I met when I was starting to work in Hollywood, who literally was humble. I do believe that people and children gravitate to good energy, and she's definitely an abundance of that," said the 36-year-old.

Defending the pop star's recent leaked version of her track "Alien" without auto-tune, Saldana said: "I'm pretty sure that 80 percent of our musical artists would be mortified if they were caught singing without auto-tune."

"She was the only pop star at that time - and I can name a lot of prominent figures right now that today are more famous than Britney - that literally got to where they were at by hating on Britney a lot."

"Because it was cool at one time to really just diss her. And Britney never did that," said Saldana.
