Get ready to find out what kind of tree Mariah Carey would like to be.

Carey is slated to give her first post-breakdown interview to ABC News journalist Barbara Walters in a "20/20" segment set to air September 12, according to ABC spokesperson Adam Pockriss.

The singer suffered a "physical and emotional breakdown" last month that left her hospitalized for two weeks and forced her to cancel all public appearances.

Carey has not yet resumed promoting her upcoming album and movie, both called "Glitter" (see "Mariah Carey's Album Release Delayed Three Weeks").

She recently paid a quiet visit to a summer camp she helps fund, and posted a cheery voice message on her official Web site (see "Mariah Carey Comes Out Of Seclusion Following Breakdown").
