The Hunger Games actress was one of an astounding 11 bridesmaids for her brother Blaine's recent wedding, featured in the latest issue of Martha Stewart weddings.
Lawrence (23) is beaming as she wears a champagne coloured gown alongside bride Carson Massler, which was shot after their October 2013 ceremony.
And she's no stranger to walking up the aisle to support her brother as previously acted as bridesmaids for her brother Ben when she was just a teenager, before hitting the big time as an A list actress.
Earlier this year, the stunning blonde actress revealed that after she's finished work on the last instalment of The Hunger Games, she'll be turning her phone off "for a year".
But movie big wigs think that could be massive mistake, as the star should cash in on her huge popularity.
"Jennifer's been working non-stop, but a whole year's a long time to not be making movies. She needs to keep up the momentum if she wants a career with longevity like Meryl Streep's," LA screenwriter Craig Victor told British magazine Now.
Jennifer shot to superstardom thanks to starring role as Katniss Everdeen in the movie version of hit book series The Hunger Games.
She has also appeared in the X-Men franchise and American Hustle and her turn as Tiffany in 2012's Silver Linings Playbook earned her a best actress Oscar.
Her relationship with British actor Nicholas Hoult is apparently one of the reason she wants to take a break, as the pair hope to spend more time together.
