The 'We Found Love' singer, 26, exposed slightly more than she intended when the front of her ethereal gown slipped down while she was posing for pictures at the Hotel Café Royal.
Although, given Rihanna has happily posed naked before and walked the red carpet in see-through clothing we don't think she'll really mind too much…
This was Rihanna's second outfit of the night, after walking the chilly red carpet at the London Coliseum in nothing but a Stella McCartney tuxedo jacket and tights.
Always one to keep all eyes on her!
Rihanna looked totally gorgeous last night, with minimal make-up highlighted her a-mazing skin. Jel!
While at the star-studded after party, the Bajan singer rubbed shoulders with a host of celebrity pals including Cara Delevingne, Naomi Campbell and bessie mate Balmain creative director Olivier Rousteing.
Rihanna referred to Olivier as her "baby daddy" on Instagram… all we can say is, we agree with all her fans who remarked they would have THE BEST looking children ever, right?!
'Diamonds' star Rihanna jetted into London yesterday morning, just in time for the British Fashion Awards, where she joined the likes of Victoria and David Beckham, Kendall Jenner, Harry Styles and Kate Moss.
