Twisters star Kiernan Shipka recounts 'Christmas mishap' that left her with 'massive hump' on her nose

Kiernan Shipka has dished on a holiday incident that led to her waking up with a facial injury.

The 24-year-old Mad Men alum recalled the moment while promoting her upcoming Christmas movie Red One at its Berlin premiere.

Chatting with People , she remembered: 'I drank so much with my friends one night, and I woke up the next day and I had — I tell you — a massive hump on my nose.'

She descriptively noted, 'My nose literally went out a little and then back in.'

The actress said, 'I don't know if I fell,' before adding that it was 'unclear how it happened' and that it 'lasted a couple of weeks.'

'It was a big Christmas mishap. You know, we live, we learn, we have fun,' the Twisters star, who turns 25 on November 10, summed it up.

Red One will hit theaters on November 15 and also stars Chris Evans, Dwayne 'The Rock' Johnson, Lucy Liu, J.K. Simmons, and Bonnie Hunt.

Jake Kasdan directed the lighthearted film and it was written by Chris Morgan and Hiram Garcia.

It follows a modern day Santa whose undercover gift-delivering organization is compromised by Grýla — a spiteful medieval force played by Shipka.

'I never really played a classic villain before,' Shipka said at her November 3 German premiere.

She expressed, 'It felt like intimidating shoes to fill. I drew inspiration from a lot of different places. A lot of random stuff.'

JK Simmons, 69, stars opposite the former child star, depicting Santa Claus.

Shipka praised the Hollywood vet, calling him an 'amazing' scene partner.

She emphasized, 'He's so supportive. I mean, everyone — it's heavyweights, this whole cast. Everyone is so good. And I was just watching, observing, exploring.'

And JK teased that his portrayal of Saint Nick is 'not what people might expect.'

He told People magazine, 'It says in the script in the first description of Santa that he's not exactly... jolly. And I thought that really helped me.'

The acclaimed actor admitted that the role was 'intimidating' because it's 'been played by some wonderful, wonderful actors.'

'I was glad that this was a very different take on it,' he shared.
