Kourtney Kardashian has revealed the name of her third child with Scott Disick; Reign Aston Disick.

Reign joins older brother Mason, 5, and sister Penelope, 2. She gave birth last Sunday, on Mason’s birthday.

Over the weekend, the Kourtney & Khloe Take the Hamptons star took to Instagram to share the first photo of baby Reign’s tiny hands and revealed his name.

“Madly in love with my little Reign Aston Disick,” she wrote.

The parents of three have been sharing their relationship troubles with fans on their Keeping Up with the Kardashians spin-off, and it seems their issues have continued even after welcoming a third baby.

Just days after Reign was born, Disick was seen at a lingerie party with Khloe Kardashian’s on-off boyfriend French Montana and Kylie Jenner’s rumored boyfriend Tyga among other guests like Chris Brown.

Earlier this month, Kardashian revealed a naked photoshoot she did for DuJour magazine, gushing about being pregnant, saying “This is what my body was meant to do.”
