The panto star is getting her 2013 off to a fresh start after leaving Assets to join the books of the Miss Universe Ireland organiser. But she admits that she deliberated over the move for some time before finally taking the plunge.
"I'm looking forward to working alongside Andrea, but this decision wasn't an easy one as I've been with Assets for five years," she said.
"This is the beginning of a new chapter in my career."
And new agent Andrea said she was "delighted" to be representing Nadia, who is now with the same agency as Rosanna Davison, Pippa O'Connor and Rozanna Purcell.
Ambitious Nadia has just finished her first stint in the Christmas panto at the Tivoli after revealing how she planned to do more performing this year.
A trained singer and dancer, she was one of the finalists in Louis Walsh's hunt for a girlband and almost made it into Wonderland.
She recently spread her wings into TV and appeared in Celebrity Salon, as well as shooting a music video for British rapper Luke Bingham.
She has been approached by a number of talent agencies in London after indicating she would consider moving to the UK to further her career.
