PICS: This is Rihanna's biggest regret in life

Los Angeles - Rihanna's only regret in life is not wearing a "bedazzled" thong with a see-through dress.

The 28-year-old singer caused a stir at the 2014 CFDA awards when she donned a sheer Adam Selman dress with nothing but nude pants underneath and she admitted she wanted to "slice her throat" for not being more daring with her choice of underwear.

She told America's Vogue magazine: "I just liked it better without the lines underneath.

"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."
