Rihanna left little to the imagination when she debuted her clothing line for River Island in London on March 4! Do you think she’s showing off for Chris Brown?

Rihanna loves showing off some sexy skin, but during her clothing launch on March 4 on Oxford Street in London, the Diamonds singer managed to bare it all while still staying covered up — her see-through black dress revealed everything, especially since Rihanna wasn’t wearing a bra!

She promoted her debut clothing line for River Island in London, and greeted fans who came from all over to see the superstar. She also presented her new line with a brief fashion show inside the store to show off her collection.

But it was her scandalous outfit that had everyone staring — under the bright lights and camera flashes, Rihanna’s dress was so completely see-through, her nipples and nipple piercing were completely visible!

Chris Brown Will Support Rihanna While She’s Touring

Even though Rihanna had to jet to London from Los Angeles, her on-again boyfriend Chris Brown will be providing unconditional love and support while she’s away for her world tour.

“They encourage each other to work hard — always. That’s how they are,” a source connected to the couple exclusively tells HollywoodLife.com. “He kicked it with her last weekend before she left, they did they thing and it’s all good. I’m sure he miss her, but they know the business and respect what each other do so it’s cool.”

Sounds like Rihanna is giving Chris a peak at what he’s missing while she’s away!
