Christina Aguilera Is Fine-Tuning Her Voice for Her Upcoming Album

Christina Aguilera is fine-tuning her voice for her forthcoming album, showing that even the divas with the most powerful singing voices sometimes need a little extra oomph. The 'Moves Like Jagger' songstress recently recruited a new vocal coach in order to perfect her pipes for her next album.

Examiner is reporting that Aguilera is working with celebrated vocal coach Seth Riggs, who has worked with Michael Jackson, Ray Charles and and Josh Groban in the past. Apparently, Aguilera is not going to "over-sing in the way that she has been criticized on her previous albums" and "she will also hit higher and lower notes."

William Orbit will also be producing Xtina's upcoming album, although the pair haven't had any in-studio time together yet. Orbit is currently working with Madonna on finishing her forthcoming LP, due out some time in the spring of 2012.

There is no word yet on when Aguilera will release her next album, but she will be returning as a coach on Season 2 of NBC's 'The Voice,' which will return to television in February 2012.
