Garner shared a sentiment post on Instagram. She shared a scene from the movie where her character Jenna Rink is dancing with young girls. The caption read:

"The movie benefitted from the performances of so many young actresses. Open and twinkly-magical then— now, 15 years later, they are ruling the world."

Ruffalo is not the only "13 Going on 30" co-star Garner had seen in the last month. In January, she shared that she met up with Judy Greer for a socially distanced walk.
