Rita Ora showed up at Nobu Berkeley restaurant for dinner last night (May 16).

The sexy singer looked a bit like Jessica Rabbit given her ravishing strapless red dress that showed off her ample bosom as she made her exit.

And it sounds like Rita had plenty of cause for celebration, as she just signed a £500,000 contract to be the new face of Madonna’s Material Girl label.

An insider told press, "They met at the Met Ball in New York last week and Madonna admired Ora's attitude so signed the idea off. Rita jumped at the chance because she's such a fan of the Queen Of Pop."
