Motherhood hasn't stopped these celebrities from running their own online businesses.
1) Gwyneth Paltrow, Goop (www.goop.com)
The actress has a 10-year-old daughter and eight-year-old son with Coldplay singer Chris Martin, from whom she separated in March.
She launched the Goop online shop in October 2012, four years after starting Goop as a weekly online lifestyle newsletter that included recipes, travel guides, shopping ideas and wellness tips.
Gwyneth says she wants to share her version of the good life with carefully curated products to help readers "save time, simplify and feel inspired".
Goop has grown into one of the most popular celebrity sites.
The online store sells homeware, accessories, kids' toys, beauty products and clothes - some of which are from exclusive collaborations with designers such as Stella McCartney.
2) Jamie Yeo, Mums (www.mums.sg)
Radio deejay and actress Jamie gave birth prematurely to daughter Alysia in November 2010.
She says her experience as a new mum - she couldn't bear to leave her daughter's side in the first two years - inspired her to set up the online shop Mums with her friend Tristan Lo, a father of two, in October 2013.
Based on a flash-sale concept, Mums stocks children's apparel, homeware, toys and accessories for mothers - including products from hard-to-find brands - at competitive prices.
It also aims to provide a platform for mums to sell their own products.
Jamie says they have more ambitious plans in the works, such as a network for her fellow entrepreneurial mums.
3) Kristi Yamaguchi, Tsu.ya (www.tsuyabrand.com)
The Olympic ice skater, who has two daughters, launched her line of women's activewear in 2012 because she felt there was a lack of functional yet fashionable active clothing for women.
"I wanted this line to inspire daily confidence; to truly help women feel great inside and out," she says.
And it's for a good cause too: A portion of all Tsu.ya sales goes to Kristi's Always Dream Foundation, which promotes childhood literacy.
