The Saturdays' Una Healy has opened up about the terrifying moment her new baby, Aoife Belle, began choking.

In an interview with Britain's Hello! magazine, the sexy singer explained that doctors had to step in following her daughter's birth and she described it as "the worst moment" of her life:

"We went into panic and pushed the emergency button and the next thing we knew, our baby was whisked away and there were alarm bells ringing and staff running around."

"I was screaming. It was the worst moment of my life. There's this precious little person who you would die for and you just can't bear to think of anything happening to her."

Healy and her fiance Ben Foden are in love with their first child, and added to Hello! that "there hasn't been a dull moment since she was born":

"During the night, I'll wake up, even when she's sound asleep, and sneak a peek. She'll be lying there, with her tiny hands up by her face - she's so ladylike - and my heart could burst with love for her."
