"I'm thrilled," the 41-year-old blonde reveals in this week's magazine, issue number 1082. "It's changed my life. I'm now a 32C and feel like I've got the breasts of a 16-year-old."
Speaking candidly about her unhappiness when it came to her old body, Ulrika explains the reasons behind her surgery decision, talks about the mental and physical process of going under the knife and reveals what her family think of her new look.
"It's all down to a healthy eating plan, gentle exercise – and reconstructive surgery," the good humoured mum-of-four - married to US advertising executive Brian Monet - jokes. "I just wanted to repair what Mother Nature had inflicted on me during years of child-bearing and rearing."
Also in this week's copy of HELLO! there's a special report on why this summer might bring testing times for royal girlfriend Kate Middleton and Tamara Beckwith celebrates her baby daughter Violet's christening day.
