Khloe Kardashian has such a subtle way about her, doesn't she?

At last night's People's Choice Awards, a reporter asked sister Kim about Kanye West, the implication being that there's something going on between she and the rapper.

"I think I've just been having a lot of fun," Kim said.

"That's because they're boning!" a nearby Khloe quipped.

"That came out of Khloe's mouth, not mine!" Kim quickly replied.

Sisters!
