Kim Kardashian
and Kanye West have gone on a few very public dates, but there's one person who's still in the dark about their relationship: Her sister, Kourtney!

A pregnant Kourtney was on "FOX & Friends" this morning, where she was grilled over her sister's blossoming relationship with the rapper.

"Well he has a 'K'," she joked -- referring to her family members having names that start with the letter "K," a coincidence that didn't work out too well with Kris Humphries.

"I think they're friends," Kourtney added, while deflecting rumors the coupling is all for publicity.

"They [tabloids] say it all," she said of the reports. "I mean they're definitely friends and have been friends for years ... I don't think so, who knows!"

How much do you think Kourtney reallllly knows?
