We think reality star Kourtney Kardashian looks darn good pregnant, but her beau and baby daddy, Scott Disick, is allegedly poking fun at her for packing on some baby weight.

An insider tells Hollywood Life that during a recent night out, Disick ridiculed Kourtney — now around five months pregnant with their second child — for her weight.  “He even told the waiter that she would have ‘a side of beef,’” the source reveals. Another source says he’s bestowed her with an unflattering nickname: “Portney” — playing on the word “portly.” 

Moreover, the insider says Kourtney is beginning to think Scott’s only in their relationship for the money, claiming that he’s tried to go “behind her back to negotiate his own deal for rights to the baby’s first photos” and says Kourt thinks Scott views Baby No. 2 as “another opportunity to cash in.”

Whether or not Scott sees the error in his ways remains to be seen, but in the meantime, the source says Kourtney won’t break up with him: “Scott gets whatever he wants because he knows she won’t leave him.”
