It's becoming harder and harder to keep up with the Kardashians these days! The famous family has been growing more and more every year now that almost all of the famous siblings are parents. Arguably the most famous family member, Kim Kardashian welcomed her fourth child, son Psalm, earlier this year with husband Kanye West but the reality star has revealed that four is definitely enough.

Kim and Kanye also recently celebrated their fifth wedding anniversary, which may be considered a pretty big milestone by celebrity standards, and to commemorate the occasion the couple renewed their vows in a ceremony so private that even E! cameras weren't there to capture it. On this Sunday's episode of Keeping Up With The Kardashians, the KKW Beauty founder explained to pastor Rich Wilkerson Jr., who performed the couple's original wedding ceremony in 2014, that she was unable to keep the vow renewal a surprise. "I, at first, was gonna keep it a full surprise and then I heard he was trying to plan something," Kim explained. "Everyone was kind of being really weird. And I was like, 'Well, guys if he's trying to plan something and I'm trying to plan something? Someone has to say something and we'll just do it together.'"

The couple decided together on a vow renewal, but Kim was still able to surprise her husband by writing her own vows for their renewal. "Kanye always talks about how, at our wedding, we had really traditional vows," Kim explained during a KUWTK segment. "Then, I'm sure he thought we should write our own vows. But, at that time in front of all those people, I didn't even think I could get it together to say original vows."

She explained to Scott Disick during the show that she really wanted to plan something extra-special for her husband because life had been so hectic for them since the arrival of baby Psalm. “Things are definitely more chaotic like all the time, but I make it a serious point to spend time with him,” she said. “Kanye knows that I’ve had such anxiety with the new baby and everything going on. He’s stepped up so much and has been the most amazing dad, playing all the games with the kids and things like that.”

Making the moment even more special was that all of their children were in attendance. “I think it’s so special that all four of our kids are here,” she said. “It’ll just be really sweet, and I’m excited that everyone is coming over.” Kim also revealed in the episode that she has enough kids to keep up with now that they added their fourth child to the family. “I feel so complete. I really do feel like four is the perfect number for me. I feel so full in the best way, but I’m done.”

She also revealed that Psalm wasn't originally going to be her son's name and that little sister Kylie helped them decided on Psalm. “His name was going to Ye, but Kanye didn’t like Ye because Ye doesn’t mean anything,” she said. “We looked up every name in the bible that had Ye in the beginning, and the only name was Yehezkel, and Kylie called at the last second and was like, ‘No!’ Psalm and Saint sound good together.”
