Katy Perry & Rihanna: Roc Nation Pre-Grammy Brunch

Katy Perry and Rihanna attend the Roc Nation Pre-GRAMMY Brunch held at the Soho House on Saturday (February 11) in West Hollywood, Calif.

The ladies both took to their Twitter accounts later in the day to post their reactions to news of Whitney Houston‘s shocking death at 48.

“NOOOOOOOO,” Katy wrote. “So devastating. We will always love you Whitney, R.I.P.”

“No words! Just tears #DearWhitney,” Rihanna tweeted. “I honestly can’t think of anything else!!! Feels so strange being at the Grammy rehearsal right now!!”

FYI: Rihanna wore Bottega Veneta while Katy paired her Fausto Puglisi dress with Charlotte Olympia shoes.
