Myleene Klass keeps in shape by mowing the lawn.
The 37-year-old singer, who has daughters Ava, eight, and Hero, four, has revealed her secret behind her svelte curves and washboard abs is doing heavy-duty housework.
Speaking to the Daily Mail's FEMAIL, she said: "House work [keeps me in shape]. Mowing the lawn, washing the windows, doing the hoovering. I find it therapeutic and also helps work up a sweat in no time; that and swimming."
She added with a smile: "My dad was a frogman in the Navy and myself and my girls spend a lot of time swimming, it's in our blood. We're mermaids."
The brunette beauty, who believes her style is "mostly classic with a little Joan Collins thrown in and a lot of Bet Lynch," has unveiled her ninth collection with Littlewoods.
The 10-piece winter line includes stunning floor-length gowns, leather skirts and figure-hugging bodycon dresses, dipped in glitter, perfect for the festive party season.
She explained: "This collection is extremely bold, vibrant and chic. It's perfect for the upcoming party season and everything you could possibly need from huge faux fur coats to brave the winter chill in, through to a stunning, leopard print maxi, which I fully intend to live in."
