The actress (20), who plays Rachel Brennan on the hit soap, was awarded a scholarship to attend The New York Conservatory of Dramatic Arts and moved to the Big Apple ahead of her first semester.
Niamh has grown up on the soap opera, after landing the role at age 11 and said her co-stars were reluctant to say goodbye to the young star.
“Tony, my on screen dad, and my actual dad have a lot in common: neither want to believe it was happening. Tony may deny this but I know the truth,” Niamh told The Sunday World Magazine.
“I want to mention everyone but they all know how much they mean to me. So I would hope it is goodbye for now and not goodbye forever. Hopefully you haven’t seen the last of Rachel,” she said.
The actress revealed that she dreaded filming her final scenes on the long-running soap opera but she needn’t have worried.
“I thought my last scenes would be tough to shoot but surprisingly it was ok. Everyone was so supportive and made it a positive thing. I won’t reveal too much about my exit storyline but it’s one you will definitely want to tune in for,” she said.
The young actress is currently living in a student apartment on Manhattan’s Fifth Avenue and said she dreams of a long career in acting.
“I would love to work alongside Tom Hanks. His work is amazing. For now though, it is strictly college and I am not thinking outside of that.”
