Bumps on parade: pregnant stars strip down

Zoe Saldana posed naked for Women's Health UK in the early days of her pregnancy, before the news was officially confirmed by the actress. "It means she has posed naked - celebrating her body doing the hardest work it can - when she could have possibly felt at her most vulnerable. Inspiring? Empowering? A little bit kick-ass? We’d say so," the accompanying article read.

Heavily pregnant singer Shakira has posed for a photo shoot in a bikini top with her partner Gerard Piqué, but this isn’t the usual semi-nude pregnancy shoot – instead, it’s to raise awareness for a new UNICEF campaign.

The Columbian singer today posted the images on her Facebook page with the caption, “The countdown begins! And we'd like to invite you to participate in our world baby shower joining efforts with UNICEF: http://uni.cf/baby.”

The link leads to the couple’s ‘World Baby Shower’, a site that aims to “help UNICEF save children’s lives”.

In a video on the site, the couple speak about their contribution to the UNICEF campaign.

“In lieu of receiving gifts for our baby as with a traditional shower, we would like to offer support for babies who live in conditions of extreme poverty throughout the world,” Pique says.

Well-wishers can donate money – in amounts as small as $5 – to help buy mosquito nets to prevent malaria, vaccines for polios, baby scales, rehydration packs and food.  

Shakira has long been an advocate for underprivileged children, founding the Pies Descalzos, an orgnisation that has helped open hundreds of schools and education centres in her native Colombia.

The photo was taken in December, and it’s believed the baby is due in the next week or so.
