Khloe bonds with her niece after boxing session

Baby North West has been getting lots of fuss from her auntie Khloe Kardashian.

Kim‘s little sister, 29, shared a picture on Instagram of her holding four-month-old North’s tiny hand yesterday, simply captioned: NW

The adorable black and white snap shows North, whose face can’t be seen, holding on to Khloé’s manicured fingers.

It’s only the third picture released of the tot – the previous two snaps were shared by 32-year-old Kim.

Khloé had earlier posted a photo of her grasping teenaged half-sister Kendall Jenner, 17, after they embarked on a gruelling workout together.

My boxing buddy @kendalljenner and I went HAM,’ Khloé wrote.

She later admitted on Twitter that the brutal sparring session had left her feeling exhausted.

Cant move my arms after that boxing class w/ @KendallJenner,’ the reality star Tweeted.

Love/hate this feeling! We accomplished something. Our faces were SOOO red LOL
