Cycle 21 of Tyra Banks' America's Next Top Model is proving that the addition of guys to the girls in competition, wasn't just a gimmick for Cycle 20. A landmark for the format having reached twenty series, it's very admirable.

Having guys and girls in competition, is a matter of 'no return' for the series. The dramas of in house romances, the exploration of gender stereotypes and eye candy for all, will certainly endure.

It will be interesting to see when the Australian version of this format will evolve to gender equality.

In 2014 the format in Australia hit an all time high with the addition of Jennifer Hawkins filling the shoes of Tyra Banks, here.

In 2015 we are poised to see an exciting range of guest judges in the Australian format, including Kim Kardashian and most importantly Tyra herself.

For fans of the show having Jen and Tyra side by side will be rapture.
