It 

looks like taking a little time off from "The Voice" gave Christina Aguilera the time and space she needed to regain her fab physique.

The "Let There Be Love" singer, 32, posted a photo of herself looking the best she's looked in years to Twitter on Wednesday from the set of the music video for "Hoy Tengo Ganas de Ti" ("Today I Want You"), a duet with Alejandro Fernández, which is a single for the Univision program "La Tempestad" ("The Storm"). The show stars former "Dancing With the Stars" hunk William Levy and 2010 Miss Universe Ximena Navarrete.

"On set shooting music video with @Alexoficial for #HoyTengoGanasDeTi," wrote Aguilera.

In other Aguilera news, reports surfaced this week that she'll be returning to her big red chair on "The Voice" for the show's fifth cycle this fall. Shakira's been filling in during Season 4, but it's always been reported the on the hit NBC show would come in and out of rotation depending on their full-time music career commitments.

At least one outlet reported that Aguilera will receive $17 million to judge the next season, but a source close to "The Voice" tells Yahoo! Music's Lyndsey Parker that the figure is more like $12 million.

That still seems like plenty of money to be able to continue working with some of L.A.'s top personal trainers!
