Miley Cyrus has denied she had a pop at Jennifer Lawrence for vomiting at Madonna's post-Oscars party.

The Hunger Games star had told Late Night With Seth Meyers about her ordeal at the awards ceremony bash, and alleged criticism from unlikely quarters.

She said: "I've never gone out after Golden Globes or Oscars or anything. I'm just so sick of people by that point. I'm like, 'Ugh, god!' But this time I was like, 'I'm going out.' And I puked.

"There's this big fancy party, this Guy Oseary and Madonna party - if you get invited, you're like, you know, super-important. And I puked, on his porch.

"I was in such bad condition, and I look behind me while I'm puking, and Miley Cyrus is there like, 'Get it together'."

But Miley, after pleas for more details from fans, apparently tweeted: "That never happened" and then deleted the tweet, according to the Daily Mirror.

J-Law also blamed her friend Laura, who she had taken to the Oscars, as the reason behind her being worse for wear.

She explained: "She was a terrible influence on me. We left and then she was like, 'Meet me at the bar.' So I snuck out and I was like, 'Oh, my god!' I can't do this!'

"And she was like, 'You can do whatever you want!'"
