Just reposting my comments on it from the KC findings on Twitter [...] thread

Looks like a McEntire-Blackstock get-together + Kelly! Aww...is that Brandon's little boy?
Unless Kelly suddenly went back to brunette, it's an older pic, but she didn't go blonde again until June, so her and BB still may've been a couple there. But, yes, where did it come from, and was there a description provided?
