Ariana Grande covers Whitney Houston at White House...

Last night, Ariana Grande performed a special concert for President Obama and the First Lady ('Women of Soul: In Performance at the White House'). Ariana performed Whitney Houston’s 'I Have Nothing', which earned her a standing ovation.

Ariana was the youngest woman there and was considered a woman of soul (debatable) alongside many vocal legends. She also performed her own song 'Tattooed Heart' off her debut 'Yours Truly'. During the finale, she performed with Jill Scott, Tessanne Chin, Melissa Etheridge, Patti LaBelle, and Janelle Monáe on 'Proud Mary'. The full concert will be broadcast April 7th on PBS.
