It's official: star model Petra Nemcova of Czech Republic is set to challenge career rivals Heidi Klum and Tyra Banks by hosting her own reality TV show on the fashion world. Meanwhile the model, who is dating James Blunt, has quashed rumors that the couple’s relationship are on the rocks.

Petra will be advising promising would-be models, who are struggling to get an assignment, with top agency ‘Next’.

The show, currently shut for TLC by 25/7 Productions in association with The Mottola Company, will be an high profile international event, and Nemcova will track the girls around the world giving them suggestions on campaigns and surviving in tough competition.

"This is a series about hopes, dreams and aspirations and overcoming the real life obstacles of the modeling industry. I'm excited to show the audience the true competitiveness and often gritty side of becoming successful in this industry," said Dave Broome, executive producer.

Rumors say that Petra Nemcov, who is dating James Blunt, seems to be failing in this relationship.
