Kim Kardashian and Kanye West not engaged - report
"She wrote me this morning and didn't mention it," Kardashian's friend Jonathan Cheban tells the Huffington Post.
Seacrest said on his KIIS-FM show that he thought West would pop the question while celebrating Kardashian's birthday in Italy.
"No one had any idea what Ryan was talking about!" another friend tells HuffPo.
Kardashian herself tweets on Monday, with no mention of a proposal, "Just got back in town & wanted to thank you all for the amazing birthday wishes! They all made me smile! I can't thank you enough!"
One marriage at a time is probably enough for Kardashian, though -- lest we forget, she's still married to Kris Humphries.
