In between cuddles with the Kardashian family's newest member, Penelope Scotland
, Kylie Jenner cradled another baby that's almost as cute – a puppy!
Jenner shared a photo on Twitter
Tuesday of herself nuzzling an adorable gray and white pup, the new pet of her friend Anastasia Karanikolao
The 14-year-old wasn't the only one fawning over the little one. Her sister Kendall, 16, with whom she shares two young Labradors
, also posted a photo of the puppy on Twitter
– sprinkled with a touch of envy.
"@stassiebabeyy's new puppy #jealous," she wrote.
