Jennifer Garner as Jenna Rink

Jennifer Garner plays the "big-time magazine editor" and totally nails the whole "30, flirty and thriving" thing.

Since dancing the "Thriller" straight into our hearts, Garner has starred in plenty of films like Peppermint, Dallas Buyers Club, Juno, Love, Simon, Yes Day and The Adam Project, where she reunited with Ruffalo.

"It was wonderful," Garner told Good Morning America of working with Ruffalo again. "We were playing a married couple and we just had this instant comfort and obviously there's just such a connection and a warmth. It was actually a really beautiful experience to revisit that relationship."

Additionally, Garner sweetly voiced Mama Llama for the animated kids' series Llama Llama and is the most relatable mom on Instagram.

The Alias star will be reprising her role of Elektra in the 2024 movie Deadpool & Wolverine opposite Ryan Reynolds and Hugh Jackman. Garner first portrayed the comic book character in 2003's Daredevil (starring Ben Affleck and Colin Farrell) and again in 2005's Elektra.

On top of acting, the mom of three founded Once Upon a Farm, a company that creates organic baby food.
