Between making an appearance at Jay Z's music streaming launch party and then stopping by Opening Ceremony for some retail therapy, Rihanna was a busy bee yesterday!

Bad Gal RiRi wore daisy dukes and a bra, and she accessorized with a hat and a crazy trench coat. Not too long ago she revealed to Vogue that if she wears a bra, she doesn't wear a shirt and if she wears a shirt she doesn't wear a bra. At first we were a bit skeptical, but we haven't caught her wearing both a bra and a shirt for quite some time now!

And speaking of Jay Z's new service, Rihanna changed her Twitter banner last night to support Tidal, which aims to put more money in the pockets of the artists. RiRi tweeted, "NAVY, turn the tide…#MakeMusicHistory #TurnitBlue #TIDALforALL." Beyonce, Madonna, Calvin Harris, Diddy and Kanye West also followed suit, and all of the stars have been promoting the crap out of the new streaming program. But will it swim or sink?
