Shakira showed off her growing baby bump in new photos showcasing the pregnant star with her boyfriend Gerard Pique and their son Milan.

The 37-year old Colombian pop singer is expecting a second child with FC Barcelona soccer player boyfriend, Pique, who is 27, E! News reports.Their son will celebrate his second birthday Jan. 22. In accompanying photos, Shakira in a pink dress posed with Pique as he placed his hands on her stomach. The singer is also seen in a picture by herself dressed in a gray gown holding a giant balloon.

The photos were posted on Sunday as a part of the family's second UNICEF World Baby Shower. Shakira is a Goodwill Ambassador for the Education Fund. The couple thought of the idea two years ago when they had their first child.

"We wanted to give something to other parents and babies around the world, who live in conditions of extreme poverty and vulnerability but whose lives can be improved greatly by small contributions from others<' Shakira said in a statement posted on her Facebook page.

The couple says their first World Baby Shower was a success. The initial shower brought in 3.8 tons of therapeutic food to battle malnutrition, nearly 100,000 polio vaccines, over 1,000 mosquito nets to protect from malaria and 200,000 rehydrating salts.

On the UNICEF website the family encouraged other parents to hold their own World Baby Showers or to give gifts to those in need.

Guests can donate "inspired gifts" from UNICEF"s gift registry. They can give food vaccines, toys and other supplies to children in need throughout the world. The prices of the gifts range from $10 to almost $2,000.

Shakira's fans were able to use Facebook's new 'Donate' button to learn more about the charity and to give a gift from the registry. From the singer's Twitter profile, users were able to purchase a special thank you card from the expectant parents. Each card would unlock funds for measles vaccines.

Shakira announced last fall she is expecting another boy.
