The Atomic Kitten star is just back from New York City, where boyfriend Charles Gay got down on one knee to pop the question.
Best early Christmas present ever, right?!
Still looking as if she's on cloud nine, popstar Natasha was among the celebrities who attended the opening night of Disney On Ice presents Frozen at the Echo Arena in Liverpool.
Natasha, 34, was joined by youngest child, daughter Ella, two, and son Alfie, six, for the festive extravaganza, which tells the entire story of Frozen with help from favourite characters such as Mickey and Minnie Mouse, Disney princesses, and famous faces from Toy Story, Finding Nemo and The Lion King.
And it's all on ice - how appropriate!
Natasha told fans that little Ella had been "so excited" at seeing the Disney movie played out live, adding: "Her first show and she loved every minute of it, great show."
Ella is Natasha's daughter with ex-boyfriend, 5ive singer Ritchie Neville. Alfie's dad is Natasha's ex-husband, businessman Riad Erraji. She's also mum to sons Josh, 13, and 11-year-old Harry from previous relationships.
Natasha was in New York City with boyfriend Charles last week when he popped the question.
Revealing her happy news to fans, Natasha said: "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!
"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."
Meanwhile, other stars in attendance at Disney On Ice presents Frozen included Alex and Steven Gerrard and Jennifer Ellison.
If you fancy seeing the show for yourself, it's running until Sunday, 4 December in Liverpool and tickets are available now at www.disneyonice.co.uk or via the Echo Arena's website and box office.

"In our more than 30 years of producing Disney On Ice shows, Feld Entertainment has been waiting for a film like this," said producer Nicole Feld. "While it might seem obvious that Frozen is well suited for the ice, this Disney On Ice production will touch audiences emotionally through innovative show elements and world-class skating."
Frozen directors Chris Buck and Jennifer Lee added: "Seeing audiences around the world embrace Frozen has been the experience of a lifetime. And to now have the chance to consult with the talented team at Feld Entertainment and watch their creation come to life on ice, is thrilling."
