Kris Jenner Opens up About Her New Grandson Saint West

— -- Saint West is just a few days old, but he's already won over the heart of his grandmother.

Kris Jenner told "Entertainment Tonight" that Kim Kardashian West's new son is "amazing."

"We've only known him a few days," she added, "so we'll see if he's calm or anxious - we'll see what kind of kid he is!"

Kardashian West, 35, and her husband Kanye West, 38, welcomed Saint on Dec. 5. Jenner praised her reality star daughter for being strong throughout the delivery process.

"She was amazing," she said. "She's a really strong girl. A little cranky when she gets uncomfortable, but other than that..."

Now, Jenner said that her daughter and her grandson are relaxing at home.

"We're happy that everyone's safe and sound and all tucked in," she said.
