Calvin Harris' ex-girlfriend Rita Ora left little to the imagination after donning racy ensembles during an opening of a restaurant in London.

The 24-year-old "I Will Never Let You Down" singer was spotted at the Sexy Fish restaurant in London for its launch party where she rocked a strapless gold dress.

Her stunning outift featured a corset style bustier which emphasized her enviable curves.

British singer Rita Ora's hourglass figure was also highlighted with fishtail hem, which suited the event's theme, making her the apple of the eye for the event.

The "Body on Me" hit maker completed her ensemble with a pair of strappy gold heels as she went out to do her performance at the party.

Calvin Harris' ex-girlfriend Rita Ora was also named as the ambassador of the new restaurant.

After her performance, Rita Ora decided to change her striking outfit for an equally racy get-up, Mirror UK said in a report.

The "I Will Never Let You Down" singer was seen going out of the restaurant in a skimpy black leotard that she paired with gold Chanel belt.

Calvin Harris' ex-girlfriend Rita Ora topped off her look with a pair of long leather jacket and sky-high black heels.

The "Fifty Shades of Grey" cast member was spotted going out of the place with her hair still pinned up in rollers as she covered her face with a pair of shades.

"How We Do" hit maker Rita Ora just came from Los Angeles after a series of promotional tours for her new single "Body on Me," which she collaborated with Chris Brown.

The Kosovo-born singer is now back in action for the "X Factor" where she recently worked with Meghan Trainor.

While all her commitments, Rita Ora is clearly focusing herself on her career following her two consecutive break-ups.

Last year, Calvin Harris took to Twitter to confirm his split with the singer.

Rita Ora meanwhile told Marie Claire, through US magazine, that their split was caused by the conflict of their personal lives and career.

"There was a reason why I split up with him," she said.

"I thought he had my back and that he'd never steer me wrong. But then 'I Will Never Let You Down' came out, and everything started to go a bit weird. I don't know if it was because business was mixed with personal or what."

Weeks after, Rita Ora moved on from her break-up as she started dating rapper Ricky Hil. But the relationship was also doomed as they also split a few months ago.
