On Sunday, Kardashian tweeted what appears to be a childhood photo of Humphries, along with the message: "I want my son to look like this!"
Her … son?
Does the reality star, 30, who's made no secret of wanting to settle down and have kids, see Humphries as father material? Or is this just a little harmless flirtation?
Either way, the New Jersey Nets star, 25, seems down with it. "Hmmm, I think I can help you out," he replied on Twitter.
The Humphries photo – a school picture in which he's smiling and looks to be about 10 – is certainly adorable. But one Kardashian fan brings up a good point on Twitter. Namely: "What if you have a girl?"
