The worst kept secret in fashion, as related to pop music, has been confirmed. The infinitely street stylish Rita Ora is the new face of Madonna's Material Girl line, the Macy's exclusive, juniors range that she co-designs with teen daughter Lourdes aka Lola.

Ora shared the good news by posting an Instagram image of herself and her new boss, who looks gorge in the photo, posting: "Joining forces with Madonna & Lola! It's Official Ritabots – I'm the new face of @MaterialGirl. #thisisamoment for me #icon #mymuse #argghhhhh #yeeeeaaahhhhhhh."

Ora is taking over for Georgia May Jagger as the latest spokesmodel. Kelly Osbourne and Taylor Momsen were previous Material Girls.

It's rumored that Ora, 22, signed a deal worth $760,000 to front the campaign!

Her Madgesty and Lourdes are over the moon about welcoming Ora to the brand, issuing a statement that read as follows:

Rita is a talented beauty but what really drew us to her is the confidence she oozes through her music and her unique sense of style. On stage or off, in photos or on the street – she’s a magnet! This is what the Material Girl brand is all about!"

That much is true -- Ora has perfected the art of street chic and urban glam with her signature sneakers and scarlet lips.

Ora will appear in advertising and print campaigns as part of her deal.

Congrats girl! Maybe this partnership will lead to Madge guesting on an Ora track or vice versa. Holla!
