Are Tony Striker and Devin Matthews twins or not? (tip @ Dutch Dude)

In the photo below, the one tip toeing to look taller on the extreme left and with a tattoo on his stomach is Tony Striker and the other one on the extreme right is Devin Matthews. Twins, right?

But, if you look at their Flirt 4 Free profiles (Tony & Devin), the two are 21 years of age but were not born on the same month.
