Kendall and Kylie Jenner are super excited to have a new niece or nephew when big sister Kim Kardashian’s little one is born in July. But these two sound just as enthusiastic about another addition to their tightknit family: Kim’s boyfriend and baby daddy Kanye West!

“He fits in great with the family," Kylie told HLN’s Showbiz Tonight. "He is definitely very family-oriented. We like him a lot. He’s very cool.”  Kendall echoed her sister’s sentiments, adding that Kanye is, “a sweetheart.”

The sisters took a much more cautious approach to what could be a touchier question: Kim and Kanye vs. Kate Middleton and Prince William! When the sisters were asked if they thought Kim’s pregnancy was bigger than the British royals, they took the high road and called it a draw. “I don’t know,” they giggled in unison, “It’s pretty close.”

Very diplomatic, ladies!
