A PEOPLE insider spilled of their "very romantic" vacation, "It's their first summer as a couple and they are having a blast."
"Pete has an intense work schedule starting later this summer, [so] they are trying to enjoy as much [time together] as possible right now," the insider explained. "They were in Tahiti for several days without the kids."
But the source insisted the Saturday Night Live star has actually enjoyed the process of getting to know The Kardashians star's four tots, whom she shares with ex Kanye West: North, 9, Saint, 6, Chicago, 4, and Psalm, 3.
"Kim trusts Pete with her kids. He is starting to spend time with them without her. She wants her kids to bond with Pete," explained the insider. "It's very important to Kim that her kids get along with Pete."
Luckily, the Staten Island native has received the seal of approval from the tykes, as the insider claimed they "love" when he's around. "He is a fun guy. He plays with them and gives them a lot of attention," said the confidante. "It makes Kim very happy that they all get along."
Now that the actor has bonded with Kardashian's family, they've started "talking about the future," the source revealed.
"Kim's relationship with Pete is very strong. Kim is head over heels. She can't get enough of Pete," gushed the source. "He treats her so well. He is protective, super supportive and just a great guy for Kim. She is the happiest."
