Lol, no matter what the circumstances you're going to add to it to try and use the 'gay' phrase because that's what you want to believe about it. THey could have decided to intentionally use a camp image, fine, but the chances are like I've said already is that with their culture and style of popular music that image is probably normal, cool or glamorous. So he could be hetero and think he's incredibly cool and hot with the sexy women dancing with him, hair and shirt and that actually does happen alot but you'd still not want to believe it just because it goes against what you decided to believe. 'But having hot ladies behind him so it's less obvious' 馃檮 please. This is Europe remember, not America - Europeans are much more open and embracing of homosexuality except the great deal of homophobes that reside in the UK of course.
The fact of the matter is that it is your opinion not a fact because if it was a fact there wouldn't be space for differing ones, there are differing opinions here.
