June 15 (UPI) -- Mom-of-two Pink shared a smiling photo of her 6-month-old son this week.
The 37-year-old singer posted the new picture of Jameson Moon on Instagram after welcoming the infant with husband Carey Hart in December.
"He thinks what I have to say is really interesting and groundbreaking," she wrote in the caption of the snapshot for her 1.9 million followers.
Pink and Hart are also parents to 6-year-old daughter Willow Sage. The singer discussed Jameson and her family's new dynamic on The Ellen DeGeneres Show in January, saying Willow was slowly adjusting to being a big sister.
"He's delicious," she told host Ellen DeGeneres.
"I do all kinds of stuff [to make Willow comfortable]," she confessed. "I literally put Jameson down when she walks in the room. I'm trying to [put her first]. She's a little weepy these days, so we're working it out."
Pink and Hart dedicated sweet posts to Willow this month while celebrating her sixth birthday. The singer treated her daughter to Rice Krispies treats at school before throwing her a big birthday party.
"Happy 6th B day to this wild child!" Hart, a retired motorcycle racer, wrote. The love I have for this crazy little human is indescribable. My life has change so much for the better since she showed up. Love you Willz!!!! Mama, you cooked a great one."
