Latino singer Shakira, who is one of the goodwill ambassadors of United Nations International Children's Emergency Fund (UNICEF), has shared her baby bump pictures for a cause - this time for the underprivileged children.

The 35-year-old singer is expecting her first child with her soccer star boyfriend Gerard Pique of FC Barcelona.

In the UNICEF campaign, the Columbian singer is seen with just a bra and her fiancé Pique is seen shirtless.

"We'd like to celebrate the imminent birth of our first child with all of you," tweeted Shakira. "Enter Shak & @3gerardpique #babyshower to help underprivileged babies & see pictures of the expectant couple."

The celebrity couple has arranged an online baby shower through a website hosted by UNICEF so that fans could buy baby gifts like mosquito nets, polio vaccines and baby weighing scales to help children in some of the poorest countries of the world.

"The countdown begins! And we'd like to invite you to participate in our world baby shower joining efforts with UNICEF," wrote the singer.
