Kim cuddles up to Kourtney's son

Kim Kardashian has made #mancrushmonday a family affair.

The reality star, 33, shared an adorable picture of her cuddling nephew Mason Disick when he was just a baby with her Instagram followers yesterday.

#MCM Mason,’ Kim captioned the cute snap.

A smiling Kim is seen holding Mason on what appears to be a boat.

Things have changed a lot since the pic was taken – Mason, the son of Kim’s older sister Kourtney, is now 4 and Kim has become a mother herself to seven-month-old daughter North West.

She’s also getting ready to marry for a third time after getting engaged to Kanye West, 36, in October.
