In the shot, Jameson is captured in one of his crankier moments, which makes the writing on his tiny outfit all the more appropriate.
"Hello, it's me. I must have cried a thousand times," his onesie reads, taking lyrics from Adele's 2015 smash hit "Hello."
The 37-year-old Grammy winner and her hubby, former motocross racer Carey Hart, welcomed their sweet new little one on Dec. 26. The pair, who married in 2006, also have a 5-year-old daughter, Willow Sage.
Shortly after Jameson's birth, the rocker honored Willow with a special Big Sister Party, complete with a scrumptious-looking caked. Mom, Willow and a bundled-up Jameson posed for a happy pic, which Pink shared with fans.
Looks like little Jameson is already bringing a lot of joy — and laughter — to everyone!
