In 2007, Fall Out Boy released a music video for their Infinity On High single “Thnks Fr Th Mmrs,” which featured a guest appearance from none other than Kim Kardashian.

Well, as it turns out, the two have still kept in touch.

"I stay in touch with her a little bit—just emails here and there," Pete Wentz tells People. "I ran into her, and she was probably the nicest person ever. She’s exactly the same as she was then, except she’s, like, a trillion times more famous."

She joined the four members of Fall Out Boy (and multiple chimpanzees) for the video and shared a smooch with Wentz. "I'm a fan of Fall Out Boy and I agreed to do it," said Kardashian in an interview with News Times in '07. 

Of course, the two now have more than just a music video appearance in common—they both have sons named Saint, too. What's better? The two exchanged gifts, with Wentz throwing in some hope for a collab for the two Saints in the future.

"We ran into her right after her Saint was born, and we’d sent her some boots that had his initials on them," Wentz tells the entertainment source. "She sent Saint Yeezys and that kind of stuff. Very sweet."

And on that music collab? "I hope they start a band one day or something!" he tells People.

Oh, and in case you need help remembering the now iconic moment, watch the video for "Thnks Fr Th Mmrs" below:

The band's new album, M A  N   I    A, is due out tomorrow, January 19, and we are beyond excited.

When talking about their new album for issue 347, Patrick Stump says this album is going to be different than anything they’ve done before.

“This [record] is the most off-script we’ve gone,” Stump tells AP for the very first story on their new album. “I want to try to invent something, because life’s too short.”
