The 37 year old popped the question to her partner Rosie Nicholl during a holiday in Gran Canaria in the Canary Islands over the festive period.
Hardwick confirmed the news, saying:, "We were in Gran Canaria on holiday and it was about 9.30 at night and I got down on one knee.
"I'd had the ring for over a year... I was very nervous."
She also revealed her plans to propose on Christmas Day had to be postponed when she found out Nicholl's sister had become engaged the same day.
Hardwick adds: "I was going to do it on Christmas morning, but then we got a phone call from Rosie's younger sister saying, 'Guess what, I'm engaged!' I thought, 'Oh, that's done that then!'"
