Beyoncé wants to have have sex outdoors.

The 'Love On Top' hitmaker - who has 18-month-old daughter Blue Ivy with husband Jay-Z - has revealed her risque, intimate fantasy.

Speaking to Flaunt magazine, she candidly admitted: ''[I would love to have sex at] The Louvre, or under the Arc de Triomphe...Paris is a beautiful, sexy city.''

The typically private singer also opened up about the couple's romance and how best to set the mood, admitting '''90s R&B'' is a must.

She revealed: ''[All you need is] a cozy blanket, red wine, fruit, '90s R&B playing on my iPod. I don't think you need much else.''

Beyoncé also appeared to shun a trend among some celebrities who embrace a gluten-free diet, instead insisting she likes to treat herself when she can.

She added: ''I'm okay with gluten. Sunday pizza is a must for me!''

While the star may now appear to be confident and open, her former Destiny's Child singer Michelle Williams recently revealed how her ex-band mate used to be self-conscious about her ''thighs''.

She previously said: ''On the outside, we were poised and smiling. But behind the scenes we had issues. I was trying to gain weight, and meanwhile Beyoncé would say, 'I think my thighs are too big.' ''
