Former Atomic Kitten star Natasha reportedly began dating Charles Gay over the summer (16) following her break-up from the 5IVE singer in March (16) after a four-month engagement.

Hamilton, 34, revealed on Instagram on Monday (28Nov16) that her boyfriend had popped the question during a vacation to New York by sharing a picture of the couple holding glasses of wine towards the camera in a toast and her sparkler can clearly be seen.

"After the most wonderful time in New York with the man I love, I was so high on life, little did I know he was planning something very special....he proposed and I said yes!," she wrote in the caption.

"I've had such an emotional rollercoaster few days @charlesgay I'll be stuck on cloud 9 for a long time...this is just the beginning of our beautiful life together. I can't wait to see what adventures lie ahead. I love u xx."

Hamilton and Neville began dating in 2013 after meeting on U.K. TV show The Big Reunion and they welcomed a daughter named Ella in 2014. They announced they had called off their engagement in March (16).

"After careful consideration, we have decided to amicably end our relationship," they said in a statement to MailOnline. "There is no one reason for the failure of our relationship. Unfortunately it's just the way things have turned out and it's no one's fault... In the interests of our family we remain good friends and we hope that people will respect our privacy at this time."

Hamilton was previously married to Riad Erraji, the father of her six-year-old son Alfie, from 2007 to 2013. She is also mother to Josh, 14, from her relationship with Fran Cosgrave, and Harry, 11, from her romance with dancer Gavin Hatcher.
