Rihanna reveals her biggest ever regret! (Photos)

The singer’s apparently poor choice of underwear is her biggest regret in life so far…

The outfit in question was a sheer Swarovski-encrusted gown the star wore to the CFDA Awards in 2014, which saw her go bra-less beneath the sheer material.

“I just liked it better without the lines underneath,” said the Barbadian beauty during an interview with Vogue.

“Could you imagine the CFDA dress with a bra? I would slice my throat. I already wanted to, for wearing a thong that wasn’t bedazzled. That’s the only regret I have in my life.”
