Cameron Diaz, Jamie Foxx on 'Annie' Singing Lessons, 'Any Given Sunday' Reunion
Cameron Diaz was admittedly nervous about singing "fairly well" for the upcoming movie-musical Annie.
"I sang in My Best Friend's Wedding. That was more true to my voice. But that's my karaoke voice, you see," she explained while on The Ellen DeGeneres Show on Monday. "I had to actually have a voice for this song, for this film. I did a lot of training — as much as I could!"
Diaz appeared on Ellen alongside her Annie co-stars Quvenzhane Wallis and Jamie Foxx, whom she also acted with in the 1999 sports drama Any Given Sunday.
Foxx also joked, "I was naked when the camera was off, because I didn't want everyone to go crazy!"
Annie hits theaters Dec. 19. Watch the video clips below.
