Her outfit for the Oscars afterparty could have been inspired by her latest movie Fifty Shades of Grey but Rita Ora has form when it comes to flashing the flesh.

The singer made a splash at the Vanity Fair bash by going knickerless in a totally transparent black dress .

Reets wore two stunning gowns for the awards before changing into this risqué Donna Karan Atelier number which showed nearly all of her bottom to the photographers.

The one-sleeved high-necked gown featured a lace train and a panel of thicker material across the front and back with see-through side panels, showing off her tattoos.

The gorgeous actress and singer, who pouted her bright red lips, blew kisses at the paps and wore her blonde hair in her regular slicked back 'do.

Rita was dripping in jewellery and opted for plenty of dark eyeliner as she fluttered her eyelashes and made quite an impression at the bash hosted by Graydon Carter at the Wallis Annenberg Center for the Performing Arts.

Since shooting to fame in 2012 the curvy Londoner, who performed her Oscar -nominated song Grateful at last night's ceremony, has rocked her own unique sense of style.

And a quick rummage through her past outfits reveals some of her raunchiest looks so far - as well as a few fashion horrors.
