WATCH: Michelle Obama delights Grammy crowd with girl power message

LOS ANGELES, USA Michelle Obama made a surprise appearance on the Grammys stage Sunday, February 10 to deliver a message of women's empowerment alongside superstars Lady Gaga, Jennifer Lopez, host Alicia Keys and actress Jada Pinkett-Smith.

"Music shows us that all of it matters  every story within every voice, every note within every song," said the former first lady, looking glam in a sparkling gunmetal pantsuit with a 1970s-esque wrap jacket.

The Recording Academy behind the awards gala has faced a barrage of criticism for not embracing diversity within its ranks, after nearly muting women nominees at the show last year.

This year, 5 of the eight nominees for Album of the Year are women: rapper Cardi B, folk-rock singer Brandi Carlile, pop futurist Janelle Monae, R&B prodigy H.E.R. and country star Kacey Musgraves.

"Thank you so much, ladies, for your light, your message of love, your sisterhood," said Keys, the first woman to helm the show in 14 years.

"Give it up for these magnificent goddesses!" said Keys. – Rappler.com
