YUMMY mummy Cecelia Ahern has revealed how she is shunning fad celebrity diets when it comes to shedding her baby weight.
The multi-millionaire author, who gave birth to her first child Robin just two months ago, said any additional pounds she carried during her pregnancy had fallen off naturally due to constant exhaustion.
The petite blonde (28) told the Diary how breastfeeding her new bundle of joy has also helped her to regain her svelte figure in record time.
Cecelia gave birth to her 6lb baby girl on December 13, one week before she was due.
The writer admitted the challenge of looking after a newborn was a lot more demanding than writing any of her seven novels, but insisted that motherhood was one of her most fulfilling roles yet.
"Oh God, I didn't do anything in particular to lose weight other than not sleep and feed the baby," she laughed.
"I get sleep sometimes, she's kind of trying to find a routine at the moment but I can't complain. I'm just in a little bubble of happiness with her. She's brilliant, absolutely gorgeous. I love motherhood, although I have great help from David. The dads always get overlooked.
"I've taken the year off writing so I'm just going to concentrate on being a mammy now, that's a full-time job, harder than writing any book."
The glowing new mother stepped out for her first public appearance since giving birth on Saturday night, when she and long-time partner David Keoghan attended the exclusive A Night For Love event at the O'Reilly Hall in UCD.
It was truly a family affair for Cecelia, who said she was looking forward to spending some time with her father, former Taoiseach Bertie Ahern, who arrived to the event alongside boxer Bernard Dunne.
She said: "It's just great to be out of the house for the night. This is our first proper night out since having Robin. I'm looking forward to having some fun."
Cecelia's mother Miriam Ahern, whom she described as a doting grandmother, was looking after Robin for the evening while the author and her beau enjoyed their special St Valentine's night out together. The couple have been going out for almost eight years and have a home together in Malahide. However, athlete-turned-actor David was remaining coy when it came to the subject of a Valentine's engagement.
"I won't be answering that one," he said, when asked about the possibility of going down on one knee.
Other well-known names and faces at the exclusive event in aid of Irish Autism Action and the Samuel L Jackson Foundation included Gerry Ryan's ex, Morah Ryan, who arrived to the ball solo.
Caroline Downey, Lorraine Keane and her husband Peter Devlin, Ronan Keating and his wife Yvonne, Louise Loughman and her hubby Stephen Byrne, Liam Cunningham and, of course, Boyzone star Keith Duffy and his wife Lisa were also in attendance.
Entertainment on the night included a performance by legendary singer Dionne Warwick, as well as an appearance by Hollywood icon Samuel L Jackson, who was co-hosting the event alongside Keith.
