Jennifer Garner has found a fun way to channel the Halloween spirit and celebrate the 20th anniversary of one of her most beloved films.

She took to social media with a video of herself recreating a scene from ’13 Going On 30′.

Garner played the role of Jenna Rink, a teenager who magically awakens an adult after she wants to be “30 and flirty and thriving.”

In the newly posted video, she replicated the scene where adult Jenna gets ready for a party, complete with Whitney Houston’s song “I Wanna Dance with Somebody” in the background and Garner wearing what appears to be the same dress from the movie.

“Happy 20th Halloween, Jenna Rink,” the caption reads.

A year ago, Garner appeared on “The Drew Barrymore Show,” where Barrymore did a retrospective of some of Garner’s work.

When they got to “13 Going On 30,” Garner said to Barrymore, “Can you take it?”

“Joy. It was joy,” she said of her character’s scene at the party. “That was joy.”

Garner said she had no idea what a classic the film would become.
