Aguilera tweeted a photo during the shoot of herself in front of a window overlooking the ocean.
The "Genie in a Bottle" singer is granting her own wishes as she hits the gym with personal trainer Tee Sorge, according to the Daily Mail.
Aguilera, 32, has taken a break from "The Voice" to get healthy and will return next season, taking her spot back from Shakira.
The video is a cover of a 1975 Miguel Gallardo hit and will be used as the theme song for the Televisa telenovela "La Tempestad," MTV reports.
