Scarlett Johansson Pregnant: Hides Baby Bump With Strange Pose, Hot Dress On ‘Captain America: The Winter Soldier’ Red Carpet UK Premiere [PHOTO]

Scarlett Johansson is about five months pregnant, but completely hid her baby bump in a hot red dress and a strange pose at the UK premiere of Captain America: The Winter Soldier. Check out the photos here!

Pregnant Scarlett Johansson hid her tiny baby bump while attending the UK premiere of Captain America: The Winter Soldier on Thursday, March 20. Johansson, 29, wore a perfect-fit dark red dress and leopard-print pumps on the red carpet at Westfield London. In a pose that Us Weekly called "statuesque" and "slightly peculiar," Johansson was able to hide her growing belly. She kept her hands on her hips and her legs crossed for several photographs.

While her strange, stiff pose was probably an effort to make her look svelte despite her pregnancy, we're sure the Vivienne Westwood's Red Label dress helped - it fit her like a glove! The gown "hit right above the knee and the silhouette of the dress featured draping on the front, giving her just the right amount of room she needs for her teeny tiny bump," Us Weekly reports.

The dress was forgiving, but somehow was able to hug her in all the right place and flaunt the curves Scarlett is known for. Scarlett also wore her blonde hair in a voluminous and effortless blowout.

In March, it was confirmed that the "Her" actress and French journalist Romain Dauriac were expecting their first child. The couple went public with their relationship in November 2012, and became engaged back in September 2013.

Captain America: The Winter Soldier hits US theaters on April 4, 2014.

Meanwhile, the Huffington Post reports that Scarlett Johansson told reporters on Thursday that she was interested in seeing a Black Widow standalone movie. Johansson plays Black Widow, or Natasha Romanova, in the Marvel Cinematic Universe, and there has been much discussion about the character receiving her own film.

"If you want to see a Black Widow spin-off movie, then I want to see it," Johansson said on the red carpet for the London premiere of "Captain America: The Winter Soldier." "We'll see. We will put the request into Marvel tomorrow."
