Watts is expecting her second child this winter with her husband, actor Liev Schriever.

Wearing clothes that are gathered or belted under the belly always looks flattering to moms-to-be. It shows off your bump without making you look bigger than you really are. You can either buy clothes that are gathered under the bump or you can do what Watts often does and use your own belt and cinch it under your bump.

You can also belt above your bump, instead of below. Click here to check out Gwen Stefani sporting this cool look.

Harmon, 36, is around 6 months pregnant with her 3rd child with NFL star Jason Sehorn. Hicks, who is married to actor Jonny Lee Miller (Angelina Jolie’s ex husband) is expecting their first child by the end of the year.

Pregnancy Fashion tip: As these two actresses show, you can look hip and fresh by either wearing a loose, flowing dress (Harmon) or a bump-hugging top. For a stylish, flowing dress check out sites like APeainthePod.com; for the perfect bump-hugging look, it is hard to beat the fit of IsabellaOliver.com.

Are you wondering when you will start to show? If this is your first pregnancy and you are in good overall shape you may not start to show until 20 weeks. If this is not your first pregnancy you will start to show around 12-18 weeks. Find out why it can differ depending on your body type and the number of times you have been previously pregnant.

Stefani looked great in a black knee-length dress, a short black cardigan sweater, black flats and her signature red lipstick. After seeing Angelina Jolie’s flat stomach 2 months after giving birth to twins, it is refreshing to see Stefani with some new-mama curves!

Pregnancy Fashion tip: Wearing a solid black color with print at the hem draws attention away from your postpartum belly and down towards your beautiful legs.

Miller recently told Ellen DeGeneres that he and Michele have picked a “normal” name for their baby, but they aren’t sharing the name or the sex of the baby. “Even your friends that don’t want to offer an opinion, they kind of do just by their facial expression,” he says.

Hicks wears a black dress that (how do I say this nicely?) accentuates the roundness of her belly. The fabric is a bit too stiff to be flattering on a pregnant woman’s figure. On a positive note, I love her accessories — the golf jewelry and green clutch — but feel like she could have done better with her dress choice.
