The actress declared that she beat Meryl Streep when she won 'Best Actress in a Motion Picture Comedy or Musical' and was criticised on Twitter for pointing it out.
Lindsay Lohan was one person who disagreed with Lawrence's handling of the triumph.
The 26-year-old tweeted: "No one should ever mess with a legend, such as Meryl Streep."
However, the Silver Linings Playbook actress, 22, explained on The Late Show with David Letterman on Tuesday that she was simply quoting a line from a movie.

She said: "It's never a good idea for me to wing it, but it was a quote from First Wives Club!
"Bette Midler was talking about a Globe - I can't believe nobody has ever done it before - where she says, 'Look what it says, it says I beat Meryl'."
Lawrence continued: "It was so perfect, and I said it. I had no idea that Lindsay Lohan would take it to the Twitterverse, is that what they call it? I'm not on Twitter, but Twitter is very upset.

"First of all, it's Meryl Streep. You can't offend Meryl Streep. And then all of the sudden I hate Meryl Streep. Is that what this turned into? I don't like Meryl Streep?
"As if I had my eyes on getting that girl forever and I was like, 'Finally! I knew it would happen one day!'
"I wanted to make a public statement and say, 'Hey idiots. It's a quote from a movie. And it's Meryl Streep'."

Ironically, Lawrence also quoted Lohan during her 2013 People's Choice Awards acceptance speech for 'Favourite Movie Actress' on January 9.
She said: "I wish this was like Mean Girls and I could just break this up and throw it on all of you."
