Kim Kardashian's Daughter North Feeds Elephant As Kanye West Dotes On Son Saint During Zoo Day

They're doting parents who relish time with their little ones. Kim Kardashian and her husband Kanye West enjoyed a family day at the San Diego Zoo with their children.

Proud dad Kanye, 40, doted on his son Saint, two, as the duo posed for a sweet father-son photo, all documented on Kim's Instagram stories on Thursday.

Kanye had his arms wrapped around his little boy as he flashed a proud smile while clad in a grey sweatshirt, bright green shorts, and a beige hat to cap off the look. 

North, four, meanwhile, clearly had the time of her life as she fed an elephant a leaf of lettuce.

The youngster placed the vegetable against the elephant's outreached snout.  

Clearly having a blast, North also flashed a peace sign for the camera as she posed beside the animal.

She also flashed a bright smile while taking a photo beside a hippo as he fed off a pile of vegetation.

'Thank you @sandiegozoo,' Kim captioned the picture of her daughter.

Not pictured during the family outing was the couple's newborn daughter, Chicago, who the twosome welcomed via surrogate in January. 

Kim has been busy with the launch of her upcoming cosmetics collaboration, so no doubt the reality star was overjoyed to play her favorite role of doting mom on Thursday.

The star and her makeup artist Mario Dedivanovic are launching a makeup collaboration, set for release on April 5; the KKW Beauty collection is called KKW X Mario.

The collection includes an eye shadow palette with 10 colors, as well as a creme lipstick and two high shine glosses.
