Scarlett Johansson "didn't like" the person she shared her "gross" first kiss with.
The 'Avengers: Endgame' star, 34, and her co-star Brie Larson, 29, have opened up about their first lip-locking sessions and both had experiences they would rather forget.
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."'
