Jennifer Lawrence looked stunning in a bright red Dior gown at the Golden Globes.

The Joy star wore a sparkling diamond choker and eye-catching gown with side cut-outs and a bare back as she strolled down the red carpet at the Beverly Hilton on Sunday.

The 25-year-old defeated BFF Amy Schumer to win Best Actress in a Motion Picture Comedy for her starring role in Joy.

Jennifer wore her blonde hair in a chic up-do and accessorized with silver-and-red heels.

The Hunger Games star chatted with singer Katy Perry, who gushed about Joy and then admitted she was wearing a ‘bump-it’ under her wig to create volume.

The down to earth Joy actress then reached out and patted Katy on the head to double-check. ‘Yes, you do!’ she laughed.

Katy also raved about the film, saying it inspired her and that she watched it alone in a cinema while wearing pink sweatpants.

‘That’s a sad story,’ joked Jennifer, adding ‘Thank you.’

Jennifer plays Miracle Mop inventor Joy Mangano in her new film.

‘I just thought it was really exciting when he called me,’ Jennifer told E! News host Ryan Seacrest of director David O Russell, who joined her on the red carpet.

‘This woman has been in in our lives almost unnoticed in a big mainstream way, and I just thought it was a really interesting story to tell, this women doing these amazing inventions.’

Director David added that he thought it was Jennifer’s most ‘mature’ work so far.

‘It was almost like a woman’s verison of The Fighter, which I made 4 years ago,’ he explained.

Jennifer faced off against friend Amy Schumer, who was nominated for Trainwreck in the Best Actress in a Motion Picture Comedy category.

Jennifer joked that she wanted to force Amy to wear the same Dior gown.

‘She’s going to have to wear Dior. I’m just going to have to have Dior make two of whatever they’re making for me,’ she joked to E! News.
