Anne Hathaway’s baby bump stole the show at Sunday’s “The End of Oak Street” premiere.

The pregnant actress bared her belly on the red carpet in a Prabal Gurung high-low halter and low-rise jeans.

The blue top, which was lined with red fabric, cascaded to the floor in the back — with the cape offset by a cropped front.

Hathaway, 43, completed her daring maternity look with a red lip and matching heels.

The Golden Globe winner was all smiles posing with co-stars Maisy Stella, Ewan McGregor and Christian Convery.

Social media users raved over the ensemble, with one Instagram user gushing, “Just because a woman is pregnant she doesn’t have to be confined to certain outfits to please other people’s perception or taste. Loving this unique styling.”

Another fan tweeted, “Bold choice to show off the bump like that – love the confident red carpet energy.”

Others, however, took issue with the Oscar winner’s jeans, claiming the “dazzling top deserve[d] a better companion.”

One insisted, “It’s a cute look, but the pants are wrong. They need to be a little bit dressier fabric.”

Hathaway, notably, hid her bump while promoting “The Devil Wears Prada 2” in May — but showed it off when “The Odyssey” came out two months later.

By that point, the Emmy winner had gone public with her pregnancy news.

“x Baby, I’m yours x,” Hathaway, who has been married to Adam Shulman since 2012, wrote via Instagram.
