WASHINGTON: R and B star Rihanna has laughed off rumours that she’s a closet bisexual.

The Umbrella hitmaker dated fellow pop star Chris Brown for two years, before their relationship came to an end this year when he assaulted her, reports Contactmusic.

The 21-year-old recently declared that she was not yet ready to date but temporarily swearing off men has only sparked speculations that she’s secretly harbouring a love for women.

Saucy photos surfaced online featuring the singer groping a female friend have further fuelled the speculation.

One pic showed Rihanna fondling the breasts of a gal pal - but the singer has laughed off the saucy snap, insisting she’s just a big flirt who appreciates the female form.

She told New York DJ Angie Martinez, “There are tons of them (photos of her grabbing boobs) online! I don’t have a lot so anytime I see a good rack (pair of breasts), I grab ‘em. Women are beautiful. I’m not into them, but they’re beautiful. Girls just wanna have fun!”
