The 'Body On Me' hitmaker has taken over from the 43-year-old television personality on the beauty show as the main judge and has been phoning her non-stop asking her for advice.

Speaking on the 'Today Show', she said: "Speaking to Tyra and having the advice, and by the way, I was on that hotline saying, 'Tyra, what do you think, what do we do?'"

The 26-year-old pop star revealed she asked Tyra if it was OK to have a crush on the competitors walking the catwalk.

Quizzed on what she asked Tyra, Rita said: "All I said was, 'Is it normal to really fall for all these girls, all of them?' You know emotionally get attached to them and their stories.

"Some of them are really giving face, showing some great model experience."

Rita - who has several lines with popular sports brand adidas - said doing the show has been a peak in her career and she is thrilled to have been given the power to find the next best model.

She explained: "It is probably one of the funnest experiences I've ever had. Being obsessed with fashion and having the chance to really find the next superstar is so exciting. It's like having the power ... the hands to really change someone's life."

It was previously revealed that Rita was the mastermind behind 'America's Next Top Model' panel shake up, as she was actually the one who approached bosses and encouraged them to employ her.

She previously said: "I'm lucky to have friends in this industry, and I thought maybe if I call them and we create a credible panel and give a different perspective of 'America's Next Top Model', I could actually be the host."
