Mistake Or Intentional? Rihanna's brea$t falls out of dress in London [see Pictures]

Is this becoming a frequent mistake?

Looks like Rihanna's boobs just can't stay in clothes any more. The singer suffered a wardrobe malfunction again at the 2014 British Fashion Awards (BFAs) after party in London when she went bra-less and her dress #2 let her nipple out!

The 26-year-old singer who is notorious for her sexy style, just couldn't stop her latest fashion accident as she celebrated with W Magazine director, Edward Enninful (won the Isabella Blow award)

After changing into a new dress for the British Fashion Awards after party, the top half of a braless Rihanna’s dress accidentally revealed her nipple.

While sitting down and posing for a sexy photo with a friend, Rihanna leaned a bit too far forward — causing the loose top-half of her dress to reveal part of her left nipple.

Thankfully, the sexy dress appears to have remained in place for the rest of the night. Yes, even while Rihanna was giving someone a lap dance!

Well two days to the award night in London, RiRi flashed her nipples beneath a see-through top while shopping for coats.
