Reese Witherspoon is taking a page out of Jessica Simpson and Hilary Duff's form-fitting maternity style books!

The pregnant actress stepped out in Los Angeles Tuesday while working her growing baby bump in a figure-hugging gray jersey dress by Vanessa Bruno. She accessorized with her favorite turquoise and gold layered necklace, round Tory Burch sunglasses, gold bangles, matching earrings and a brown Chloe purse.

Expecting her first child with hubby Jim Toth, the This Means War actress, 36, has been loving her third pregnancy.

The pair celebrated their one-year wedding anniversary, their baby news and the Easter holiday in Costa Rica with Ava, 12, and Deacon, 8, her kids with ex Ryan Phillippe, where she rocked her baby bump in a one-piece bathing suit!

The star "is confident about her body," a source told Us Weekly. "Reese is really excited to be pregnant again!"
