The Kardashian clan has a new family member and – surprise! – he’s already causing drama.
Khloé Kardashian Odom, 28, Kendall Jenner, 16, and Kylie Jenner, 15, have adopted a rescue puppy together, and the sisters are considering themselves the dog’s three moms.
“Meet our new rescue pup!!!” Kendell Jenner Tweeted Tuesday.
Soon after they announced his arrival on Twitter, his name became an issue. Khloé revealed that the trio couldn’t decide what to call him.
“We are having a debate on his name LOL to be continued,” she wrote.
Khloé later updated that the sisters were debating over three names, but that it would be “settled soon.”
Turns out age didn’t give this older sister any seniority.
“I was overruled on the name LOL my names are too cray I guess. His name is Jackson. #3Moms,” Khloé Tweeted finally.
Luckily, the adorable puppy has other furry friends to turn to in this household of opinionated women: Kendall and Kylie each received puppies for Christmas last year.
