Got it wrong: Jennifer Lawrence admitted during a chat show appearance on Thursday that her water symbol tattoo was wrong

But she admitted that she got the ‘2’ in the wrong spot – above the other characters, rather than below – telling host Conan O’Brien: ‘It’s H-squared.

‘I didn’t go to school!’ she added as an excuse. ‘I’m an uneducated idiot.’

Luckily for Jennifer, her tattoo is tiny – and also the color of ‘a scar’ so is barely noticeable.

But in a cruel twist, co-stars Liam Hemsworth and Josh Hutcherson both backed out of the pact and never even got there tattoos inked on.

‘Everybody was getting tattoos and I was like, “I don’t want to get a tattoo” so I got one the color of a scar,’ Jennifer told Conan.

‘I got it wrong – and then Liam bailed and didn’t tattoo, and Josh never got one either.’

‘What – they said, “You go first” and then they didn’t do it?’ Conan asked, amazed.

‘I’m the goose, yeah,’ admitted Jennifer.

Despite the apparent deception, Jennifer seemed emotional talking about the end of the series, calling the final shoot days ‘really emotional.’

Getting emotional: Jennifer said it was hard for the cast to let go of each other

‘We didn’t want to let go of each other, me and Josh, Woody and Liam,’ she said.

‘Josh and Liam and I got really codependent towards wrapping and we’d change call times and ride in the same car and wouldn’t be anywhere apart.

‘So then we kept getting anxiety about leaving the apartment. And eventually we didn’t, and we all just held each other, and slept. We just held onto each forever.’

However, despite her clear affection for him, she also insisted Liam was ‘an animal,’ adding: ‘His family is the craziest family I’ve very been around in my life.’

‘The way they communicate. It’s physical and crazy,’ she explained. ‘It’s like, “Eat this scab and I’ll give you five bucks!” They’re disgusting! They’re real animals – they’re bears.’

While she was clearly sad at shooting finishing, she admitted she will be more than happy to see the promotion of the final movie, Hunger Games: Mockingly, Part 2, ending.

‘It’s exhausting,’ she said. ‘They pushed this show pony too far. We’ve been everywhere.

‘I just don’t know how to talk about the movie anymore. It makes her sinuses hurt.’

She also showed off a video someone shot of her excitedly bouncing on her bed as she got her first night of sleep during a 12-hour flight in the middle of promotional duties.

’This was my first night of sleep because we couldn’t sleep in the hotels so the best night night of sleep I got was on the plane,’ she explained, adding that she ‘actually dislocated my toe by hitting my own foot’ during the night.

Of all the tour, she admitted the strangest place to visit was China.

‘They call me Big Elderly Cousin – I’m super flattered,’ she said sarcastically.

The actress wore leather trousers for her chat show appearance – soon calling it ‘a big mistake.’

‘I don’t know how I’m going to sit to look demure and thin,’ she said. ‘I’m like slipping all over because of the leather.’
