"Alicia Keys and Tyler Perry are among the celebrity guests who will appear on the new season of America&amp;#039;s Next Top Model. The show, which returns in August, will feature a cast entirely made up of college students.   Host Tyra Banks has now told TV Guide that Keys will appear to mentor the hopefuls in one episode. She added: &amp;quot;Tyler Perry comes on and gives the contestants an acting challenge. The winner of that acting challenge is actually going to be in a Tyler Perry movie.&amp;quot; Banks also revealed that 90210 star Shenae Grimes will photograph the models for one shoot, saying: &amp;quot;[She] actually took some really beautiful pictures.&amp;quot;   Banks has already explained changes to the America&amp;#039;s Next Top Model format this season, which will include audience participation for the first time. Meanwhile, the judging panel has also been shaken up, with Rob Evans joining the show. The news came after Nigel Barker, Jay Manuel and J Alexander - who had all been a part of America&amp;#039;s Next Top Model since the beginning - announced their exits earlier this year.
