While participating in an Instagram Live Monday night, the "Marriage Boot Camp" star played a game of "F--k, Marry, Kill" with a few friends. O'Day, who is a member of the girl group Danity Kane, was asked to either "f--k," "marry" or "kill" three famous female bands -- Spice Girls, Fifth Harmony and Pussycat Dolls.
Cabello, who left the girl group back in December 2016, has seen her hit "Havana" from her first solo album become Spotify's most-streamed song by a solo female artist in its history. The pop song won Video of the Year at the MTV Video Music Awards. Cabello took home a VMA for Artist of the Year, as well as four American Music Awards in October.
Fifth Harmony continued on without Cabello and recorded another album, but eventually the band broke up and announced an "indefinite hiatus" back in March. Like Cabello, Normani Kordei, Lauren Jauregui, Dinah Jane and Ally Brooke all went on to pursue solo careers.
