'13 Going on 30' star is all grown up and hilariously recreated movie’s iconic Jennifer Garner scene

It’s one of our favourite coming of age rom-coms, starring the one and only Jennifer Garner.

But now 13 Going on 30’s other star Christa Allen – who played the younger version of Garner’s character Jenna Rink – is all grown up and looking like Gardner’s doppelganger!

The actress, who is now 28 years old, debuted in the 2004 flick playing the 13-year-old Jenna, but in a hilarious new video, the actress has filmed herself dressing up as the adult Jenner, set to the tune of Whitney Houston’s I Wanna Dance With Somebody, recreating one of the flick’s most iconic moments.

"Jenna Rink forever," Christa captioned the cute clip on Instagram.

How fun is that?!

Here’s the original scene from the movie for comparison:

13 Going On 30 was directed by Gary Winick (Bride Wars, Letters to Juliet), also starred Mark Ruffalo, Judy Greer, and Andy Serkis.
