Her famous figure has set hearts on fire across the world, but seems Scarlett Johansson has lost more than her blonde locks.

The far less curvacious star stepped out on the Los Angeles, California, set of Captain America on Tuesday a shadow of her former self.

Renowned for her more than ample bosom, the star appeared decidedly smaller in the chest area as she wore a tight black tank.

Missing something? Renowned for her more than ample bosom Scarlett Johansson appeared decidedly more flat chested in a tight black tank on the set of Captain America in Los Angeles, California, on Tuesday

But her curves were not the only thing missing.

The actress also has had to dyed her golden tresses red again as she reprises her role as the Black Widow for the latest Captain America sequel.

Just two weeks ago, the 28-year-old was seen with her blonde hair and on Tuesday, it was a very different story.

New look: Scarlett has also had to dye her hair red to reprise her role as Black Widow

Not for the role: When playing Black Widow before in The Avengers the star certainly had plenty of curves

The star – whose character Black Widow was not in the original Captain America – did not look in any hurry to start filming.

At first the star emerged from her trailer wearing what looked like yellow pajama pants with a black tank.

She also showed off her a temporary tattoo on the inside of her arm that has to be applied every day for her to play Soviet spy turned hero Black Widow aka Natalie Romanova.

The actress did manage to drag herself out of her sleepwear and into costume but the new look was hardly a style stretch for the 28-year-old.

For her role – which she also played in Iron Man 2 – the actress donned tight black jeans with an equally tight tank showing off her famous curves. The wardrobe department also added knee high black boots and an army jacket.

Despite having to have her face on camera, Scarlett’s make-up was understated, allowing her creamy complexion to shine through.

The star’s pale skin also made her newly dyed hair pop even more.

The vibrant red tresses were parted down the middle and cut into a just below the shoulder bob.

Still new: Clearly Scarlett is still getting used to the new ‘do as she ran her hands through her hair and twisted the ends of it around her finger a number of times

Also on the set Tuesday was Samuel L. Jackson who is reprising his role from The Avengers, Nick Fury.

The star made sure to stand out were a luminous blue zip-up hooded sweatshirt with bright purple tracksuit pants, high top sneakers and round lensed glasses.

All business: Actress Cobie Smulders was also ready to film on Tuesday

The pair headline the A-List cast of Captain America: The Winter Solider which, unlike the original that was set in WWII, takes place in present day.

The massive gap in time is because the new film is about after Captain America, played again by Chris Evans, awakes after being frozen in ice.

The before: Scarlett, seen here in February with Jimmy Fallon, is usually a blonde
