Colton Haynes shirtless – hot or not? Colton Haynes shirtless vs. Justin Bieber shirtless – who looks better? Colton Haynes shirtless looks better, of course, which is hardly surprising given what we know about Colton Haynes’ workout and Colton Haynes’ diet, but does he look better than Zac Efron shirtless? Zac Efron’s diet and Zac Efron’s workout are no joke.
It is hard to say who looks better without a shirt. Zac used to be smaller than Colton. These days Zac is bigger than Colton, but Colton looks “drier” and more defined. They both look good, but most women would probably prefer Haynes. Why? Because they seem to be threatened by men with a pretty good amount of muscle mass. Some like it, of course, but it seems that most women prefer skinny guys. I am not sure I understand why men who have slim bodies and very little visible muscle mass are attractive. Not all women are like that, but a lot of them are. [source: Us Weekly]
