Rihanna just revealed that before she goes out to a big event, she will check with Katy Perry and Lady GaGa to see if they are wearing something similar.

In an interview she says:

“My worst nightmare would be a clash on the red carpet – so we all text each other before to make sure.

We’re all kind of fearless with fashion. So Katy and I speak all the time about what we’re going to wear. And Gaga.

One time we were going to the Met Ball, and Katy phoned me to check. We were like Oh My God, we were both going in this dress by Dolce and Gabbana with Marilyn Monroe’s face all over it.

She was like, ‘You can’t. I’ve had my nails done in mink and it matches the dress. I thought, seeing as she’d gone to all that effort, I’d let her wear it.”

Rihanna was photographed heading into the Jean Paul Gaulthier store while in Paris, today.
