Gaga will join Jimmy Iovine in the studio to help Lauren Alaina, James Durbin, Scotty McCreery and Haley Reinhart prepare to sing songs by Jerry Leiber and Mike Stoller. Reinhart performed the singer's unreleased track "You and Me" on Wednesday.
The 25-year-old has had a busy week: She released her music video for "Judas" and her HBO concert special airs Saturday.
