Scarlett Johansson "didn't like" the person she shared her "gross" first kiss with

Appearing on 'The Ellen DeGeneres Show' on Tuesday (23.04.19), Scarlett - who portrays Black Widow in the forthcoming Marvel movie - confessed: "I remember my first kiss but I didn't like the person I kissed ... I don't remember if [it was a french kiss].

"It was one of those gross-in-between ones!"

Whilst Brie - who plays Carol Danvers, aka Captain Marvel - had no recollection of her first smooch.

She said: "I guess I blocked it out! Does that mean it was bad? It definitely wasn't good."

She added: "I feel like if mine was like that I would have remembered it! So mine was probably just super benign."

The 'Captain Marvel' star also awkwardly forgot how she first met her co-star, with Scarlett pointing out: "You don't remember how we met?"

She replied: "I do, I thought you didn’t?"

The '21 Jump Street' star then proceeded to ask Brie again: "How did we meet?"

However, she said it was at a New Year's Even dinner, which according to Scarlett was incorrect.

The latter reminded her: "We worked together!"

Meanwhile, Brie discussed how surreal it is that 'Captain Marvel' raked in a billion dollars worldwide at the box office.

She said: "I just think that number is so funny.

"I feel like a billion dollars is something you say in hyperbole, like, 'It made like a billion dollars' like it made a lot of money ... but no, it actually made a billion dollars."

The actress also admitted it was a stressful experience trying to juggle the scripts for 'Endgame' and Captain Marvel'.

She said: "I was very stressed about it.

"Everyone is like, 'So, what are your powers', and I was like, 'I don't know. I'm not sure where I end up with my origin story."'
