Bad Girl Rihanna is back. Savage X Fenty made our week 100 times more fun by posting photos on Instagram of founder Rihanna posing in a new Valentine's Day collection.

The three posts show her posing in a hot pink low-cut bra and matching undergarments with garters and thigh-high sheer tights. (Don't worry, I'll be adding them all to my cart soon.)

She was perfectly glamorous, with summery blonde highlights framing her face. Her pink lingerie matched perfectly with her pink nail polish and frosty lipstick.

We're obsessed with her hand-tattooed look, which was set off by a hot pink bra.

This is much more dressed up than when we saw Rihanna on a recent trip to Aspen where she met Kyle Richards.
