Fifthy Harmony's Ally Brooke Performs "Besame Mucho" with Placido Domingo

The ladies of Fifth Harmony never cease to amaze. Like an Avengers-style squad made up of members with vastly different super powers, each time they step out on their own the core four do the unexpected. Case in point: on Wednesday night (Jan . 24) Ally Brooke took the stage in her home town of San Antonio to join famed opera tenor Placido Domingo's sold-out show at the Lila Cockrell Theater as part of the city's Tricentennial celebration.

Backed by a 64-person concert orchestra, the dynamic duo performed the beloved Consuelo Velazquez classic "Besame Mucho," with Brooke -- dressed in a flowing white ball gown -- easily holding her own alongside the legendary 77 year-old opera icon as they took turns singing the song's swaying Spanish-language lyrics about wanting an abundance of kisses.
