Singer Pink gives birth to a baby boy and shares their first photo together.

US singer Pink gave birth to a baby boy, Jameson Moon Hart, on Boxing Day. She shared the first photograph of her and her newborn this morning.

The black-and-white photograph of Pink snuggling her baby is simply captioned “Jameson Moon Hart 12.26.16”.

Soon after, the 37-year-old singer shared a second snap of her husband, motorcycle professional Carey Hart, 41, holding Jameson, captioned: “I love my baby daddy”.

The pair have been married for 10 years and Jameson is their second child together. Their daughter, five-year-old Willow Sage Hart, was born in 2011.

Pink, real name Alecia Moore, surprised fans with the news of her pregnancy in November, posting an image of herself with Willow and a significant baby bump that she had somehow managed to keep under the radar.

In 2013, when Willow was two years old, Pink spoke about her wish for her daughter to have siblings during an interview with Billboard.

“I could just as easily have [only Willow],” she said. “We could travel the world together forever. But my brother is everything to me. So I want her to have family beyond her Papa and me. For that reason, I mostly want another one for her to have a lifelong friend.”

“Family is the most important thing. I love it—it’s like holidays, the chaos, the fighting, the mum always having a kid around. For sure. I want to adopt, I want to have more—just, yes.”

Three years later, and that wish has come through. Congratulations Pink, Carey and Willow!
