Jennifer Lawrence repeats last year's Oscars fall as she trips over gown on red carpet...

Her fall on the way to accepting her Best Actress Oscar last year was arguably the most talked about moment of the ceremony.

And perhaps Jennifer Lawrence - who is nominated in the Best Supporting Actress category for American Hustle - sees falling as a lucky charm.

The 23-year-old tripped over her strapless orange gown as she climbed out of her limousine,but was helped to her feet by her boyfriend Nicholas Hoult outside the Dolby Theatre in Los Angeles on Sunday.

The Oscar winner brought her trademark humour and poise to the incident, laughing hysterically as she stood up and kept walking.

The moment harkened back to her trip up the stairs at last year's ceremony.

Jennifer was seen momentarily hanging her head in her hands after her voluminous strapless Dior Haute Couture gown caused the mishap on the steps.

Both Jennifer's Silver Linings Playbook co-star Bradley Cooper and her X-Men: First Class co-star Hugh Jackman were seen rushing to the actress' rescue.

But Jennifer was quick to rectify the situation, declining any help as she picked herself up and continued to accept the award.

As she got back onto her feet, the star-studded audience gave the actress a standing ovation - much to the actress' embarrassment.

Despite her initial blushes, Jennifer quickly laughed off the incident and began her stream of thank yous.

'Thank you so much,' she told them. 'This is nuts. You guys are only standing up because I fell and you feel bad. That was embarrassing.'

On Sunday, the star stunned in her figure-hugging floor-length gown, which featured a slight mermaid-train and swaths of material at the hips.

She wore a $2M Neil Lane platinum diamond necklace with carved rock crystal, platinum and 10 carat diamond stud earrings and a $1M platinum and diamond ring set with three fancy colored diamonds

The star wore her short blonde hair in a voluminous back-combed style and kept her make-up fresh and natural, opting for a rose lip.

Along with being nominated, Jennifer will also be presenting the Best Actor Oscar to the lucky winner.

The actress has picked up a slew of awards this season for her portrayal of unhappy wife Rosalyn Rosenfeld in the critically-acclaimed David O' Russell directed film.
