She said: "Victoria Beckham always looks so polished even with all those kids and that huge empire she runs. I look like death after a flight. There are some weeks when I don't wash my hair for days! How does she do it?"
Abbey said that when she had her daughter Sophia 18 months ago, she was determined that motherhood wouldn't come at the expense of looking good.
"When I had the baby it made me want to make more of an effort because I think it's so easy as a new mum when you're tired to let yourself go," she said.
"For your own sanity it's good to make an effort, get your nails done, have a spray tan. I think it's important for yourself, and your relationship as well, to keep trying.
"Don't get me wrong, a lot of the time I look like a complete scruffbag round the house. But if you look tired and messy then you feel like that and it's easy for a new mum to get depressed."

"It was a shock how hard it was because I saw my mum raising four kids on her own and she made it look so easy," she said.
