It was a little too big to fit into a red carpet-worthy clutch bag.

But with a five-month-old at home, Scarlett Johansson had no choice but to take her breast pump with her to the Oscars.

The actress has revealed she managed to smuggle the machine into the 2015 ceremony with the help of pal Kelly Ripa, but disaster followed when Mark Consuelos unknowingly took the bag to a party.

‘I had to bring my breast pump, because I was nursing and every ounce is like liquid gold,’ the actress tells Marie Claire, on whose March cover she appears.

‘Somehow, Mark got ahold of my breast pump—in a bag with all the milk, ice packs in there, and shit. He grabbed it out of my hand,’ she said.

‘He was just trying to help but our cars got separated. Apparently, Kelly looked over, and she was like, “Wait a minute—is that Scarlett’s breast pump? We’ve got to get it back!” because she knew how panicked I would be.

Not the highest paid: In her interview Scarlett also addressed inequality in Hollywood

‘We finally ended up at the same party three hours later, and Mark was like, “I’m so sorry.”‘

Scarlett’s daughter Rose is now two. It was announced last month that the actress had split from her daughter’s father, Romain Dauriac, last summer.

In her interview Scarlett also addressed inequality in Hollywood.

Despite being the highest-grossing actress in the industry, she still finds herself struggling against discrimination, she revealed.

‘Some people felt I should talk about my personal struggle in order to shed a spotlight on the greater issue,’ she said.

‘Maybe I’m being presumptuous, but I assumed it was obvious that women in all positions struggle for equality. It’s always an uphill battle and fight.

‘My experience with my close female friends and family is that the struggle is real for everybody. Everyone has been discriminated against or harassed – sexism is real.’

And the 32-year-old said she had to fight to get equal pay, just like any other woman. ‘Just because I’m the top-grossing actress of all time does not mean I’m the highest paid,.

‘I’ve had to fight for everything that I have. It’s such a fickle and political industry.’

Scarlett, whose twin brother Hunter worked for Barack Obama during his 2008 campaign, also talked about celebrities getting involved in politics.

‘[I believe] that it is really important to hear people in various positions of power voice their opinions, their story,’ she said.

‘Why can’t I have the voice? Why can’t I use my platform? What’s the point of having it if you don’t use it?’
