Kourtney Kardashian has kept her baby son Reign out of the spotlight since he made his way into the world at the end of last year. But it seemed that the youngster just looked too cute on Saturday and proud mum Kourtney couldn't resist sharing a photo of her son.
The picture, which is only the second snapshot Kourtney has shared of Reign's face since his birth on 14 December 2014, shows the five-month-old wearing an adorable bunny rabbit hat.
"My RAD little bunny," Kourtney captioned the photo, referring to Reign Aston Disick's initials.
Given how rare the photo of Kourtney's youngest is, it was unsurprising that her Instagram fans left 14,700 admiring comments and liked the image over 941,000 times.
Kourtney, who is also mum to son Mason, five, and daughter Penelope, two, with her long-term partner Scott Disick, is notoriously private about her children.
It wasn't until April that Reign made his Instagram debut, with 36-year-old Kourtney uploading a snap of her second son with the caption: "My little turtle dove angel baby boy Reign Aston Disick."
While the reality TV star waited four months to show her son's face in a photograph, she was announced the name that she and Scott had chosen for their new arrival a week after he was coincidently born on his big brother Mason's fifth birthday.
"Madly in love with my little Reign Aston Disick," she wrote on Instagram.
Kourtney's famous family were thrilled that Reign and Mason share the same birthday, with a source telling E! News: "The family is freaking out with joy. What an amazing coincidence."
Reign recently joined his mum, dad, brother and sister on an exotic trip to Mexico.
Scott, 31, shared a photo of Kourtney on a private jet and paid tribute to her parenting skills.
"The best thing in life is free and it's right here. Happy Mother's Day!" he wrote.
