In Pete Davidson's defense, when it comes to keeping up with the Kardashians, there is a lot to know.
And though the Saturday Night Live alum has been dating Kim Kardashian since last fall, he apparently doesn't have the family tree memorized just yet.
Kim took to Twitter on June 17 to share a "funny fact" about Pete, revealing he didn't know the real name of Kourtney Kardashian and Scott Disick's youngest child.
"Pete thought Reign's name was Raymond for the longest time," she wrote, "because that's what @ScottDisick calls him all the time."
Fans got to see the nickname firsthand during the season finale of Hulu's The Kardashians. While filming in the yard, Scott did in fact call his youngest son Reign Disick "Raymond" many times while the 7-year-old played on the trampoline with his 9-year-old sister, Penelope Disick.
Kim had plenty more post-show commentary to give to fans on Twitter. The SKIMS founder also called out Scott for saying Pete brings out a "different" side to her when she is around him. As he told Khloe Kardashian in the finale, "[Kim] says, like, young slang words" when she's around the comedian.
"WTF a is @ScottDisick talking about," Kim wrote in a separate tweet. "LOL I use new slang words?!?!"
And while most of her Twitter hot takes were all in good fun, Kim shared that not every bit of this episode was a joy to see, especially the moment Khloe had learned that her off-and-on boyfriend Tristan Thompson had fathered a child with another woman.
"This episode is really hard to watch because I am so protective of my sis," Kim wrote, "but I know she knows she can lean on us for anything."
Now that season one of The Kardashians has come to a close, fans will simply have to wait for the series' return to see what drama they're dealing with next. In the meantime, Pete can make some flashcards and lock down everyone's names before season two!
