Jennifer Lawrence has joked she gets "Lindsay Lohan grade exhaustion" but without "drugs or alcohol".
The 'Hunger Games' actress revealed she always feels tired and vomits regularly, but believes throwing up is her body's way of telling her to slow down in her life because otherwise she would just keep working.
She said: "I puked yesterday. I'm a puker. I'm a big-time puker. I think I have, like, nervous ... I think that I don't stop working, because I'm a show pony. I don't have a choice.
"So, I just keep going, I think, until eventually my body's just like, 'If we don't make her barf or pass out, she won't stop.'
"I get, like, Lindsay Lohan grade exhaustion, but without any drugs or alcohol. I'm always in bed early, but I'm still tired."
As well as the bizarre reference to Lindsay - who previously struggled with drugs and alcohol, once admitting she tried "cocaine with alcohol", but has since left her troubled past behind - Jennifer told how she kept vomiting before a kissing scene on her latest movie 'Joy'.
Speaking on 'The Late Show With Stephen Colbert', she added: "I got a stomach virus. I was puking and the poor guy - I had to make out with somebody - we were like spinning and I'd start puking and then I'd like do mouth wash and be like, 'Hey, you ready?' Licking my chops like, 'Ugh, let's do it!' "
The vomiting continued after the movie as Jennifer attended the premier of 'Joy' on Sunday (13.12.15) and unbeknown to her legion of fans, she was puking just moments before she stepped onto the red carpet.
A source close to the 25-year-old beauty revealed: "She was ill and vomiting ... but she's feeling much better."
