Shakira Shares Her Ultrasound Photo

She's already revealed the baby's gender – but now Shakira is sharing something a bit more personal: an ultrasound photo of her son.

The pop star's boyfriend, central defender for FC Barcelona Gerard Piqué, posted the photo to his WhoSay account (see it below), alongside the caption: "His first pic! #excited #cute."

Shakira, 35, and Piqué, 25, haven't been shy about documenting the pregnancy on social media. In November, she posted a photo of the two of them snuggling and showing off her growing baby bump. "I could have another nine months like this," the mom-to-be wrote at the time.

Still, that hasn't stopped her from performing in concert – with her belly on display for fans.

In September, Shakira confirmed the news that she was expecting her first child, writing on her official website, "Gerard I are very happy awaiting the arrival of our first baby! At this time we have decided to give priority to this unique moment in our lives and postpone all the promotional activities planned over the next few days."
