OMG! Stephanie Tanner and Al Lambert are friends! Former Step by Step actress Christine Lakin posted then and now pictures with Full House's Jodie Sweetin via Instagram on (TGIF!) Friday, July 25.

"Meant to post this yesterday- come on, we just get better with age right? Or at lease our outfits do :) @joditweetin," Lakin, 35, wrote. Alongside the caption, the brunette star posted a throwback picture of the gals from the '90s, cropped next to one from present day.

The childhood stars were not alone, however. Sweetin, 32, and Lakin were joined by another '90s star, Beverley Mitchell!

"Always fun hanging with these fabulous ladies @yolakin @jodietweetin," the 33-year-old 7th Heaven actress, a.k.a Lucy Camden, tweeted.

Sweetin added: "Had a great lunch with @beverleymitchel and @yolakin !! Love to see my girls!!"

Full House ran from 1987 to 1995, which overlapped with Step By Step's run from 1991 to 1998. Both family sitcoms aired during ABC's "TGIF" Friday night lineup. The WB series 7th Heaven premiered in 1996 and ended in 2007.
