Yes, Jennifer Lawrence has affirmed that she grew up with Liam Hemsworth.
During a 2015 appearance on a television talk show, the acclaimed No Hard Feelings star revealed that she and Hemsworth "grew up together." This statement was made in the context of her discussing a past off-camera kiss with Hemsworth, where she also playfully remarked on his appeal. Their shared professional journey, particularly their prominent roles as Katniss Everdeen and Gale Hawthorne in The Hunger Games film series, likely contributed to this sense of having matured alongside each other in the entertainment industry.
