Mariah Carey may need to start loosening her dresses a little.
The singer appeared on "Good Morning America" on Friday -- but before she sang, her breasts almost made an impromptu appearance of their own!
Mimi's sequined gown was so tight, the back burst open, leaving her ample cleavage without any support.
The wardrobe department ran on stage and started stitching her back into her dress, all while doing a live interview with Lara Spencer!
It was definitely an embarrassing moment, but Carey pulled it off.
