Kardashian mama Kris Jenner would also be behind her daughter if she and West got married.
"Anything that makes Kim happy, I'm thrilled," Jenner told us last night at Kylie and Kendall's Seventeen magazine cover party in L.A.
"You know what, I don't even have an answer for that," Jenner laughed. "That's so crazy, I really don't know. I think that as long as the kids are happy, I'm happy. Whatever floats their boat."
And don't count on a Kim and Kanye Keeping Up With the Kardashians spin-off anytime soon. "I think they're kind of busy right now," Jenner said.
Meanwhile, Jenner also gushed over daughter Kourtney's new baby daughter, Penelope. "I'm so content right now," she smiled. "Kourtney's such a great mom and we have such an amazing family. Penelope is such an amazing addition, so I'm thrilled."
Keeping Up With the Kardashians airs Sundays at 9 p.m. on E!
