We're no body language experts, but note how Kanye, 34, a rare smile on his face, rests one hand possessively on Kim's knee while she checks out the fabric on his upper thigh.
By the by, West was wearing that same unusually large smile while walking hand in hand with Kim that evening, and gentleman that he (apparently) is, he even made sure Kim didn't trip over a curb in her high heels.
It was their second well-documented date in two days: They also ventured out on Saturday to do some shopping, hitting the high-end racks at Balenciaga.
"It's a really good friendship that went into dating," Khloe told Us Weekly at the opening, adding that Kim's weekend accessories -- gold and diamond earrings spelling out "KW" -- "pretty much confirmed" the romance is in full swing.
"We've known Kanye for like nine years," she added to Andy Cohen on "Watch What Happens Live." "He's great with the family, but again, we've known him for so long. It's not like some stranger getting into a hurricane."
And while Khloe downplays the current seriousness of their connection, she's not ruling anything out: "Because they've been friends for so long, it's just so easy and that's something I love seeing for Kim -- the easiness and how happy she is."
