Jennifer Garner is celebrating her Alias costar Victor Garber!

The Yes Day actress, 51, posted a sweet tribute to her former costar and onscreen father Garber on Instagram Saturday, as the actor rang in his 75th birthday.

“Everything’s better when I’m next to you, Spy Daddy. Happy Birthday, @therealvictorgarber! 🎈♥,” Garner wrote, sharing photos of herself and Garber.

In a first image, the pair posed for a montage of black-and-white shots that showed them laughing and chatting together. In one of the shots, Garner fondly rested her head on Garber’s shoulder.

A follow-up photo showed the actors posing together as Garner sat in an armchair, while Garber stood behind her. Next, the former costars were seen in another throwback image in a joint selfie, which appeared to have been taken on the set of Alias.

Garner starred opposite Garber in the ABC spy drama Alias from 2001 to 2006. The pair have remained close friends over the years.

Back in January, Garner had an Alias reunion with Garber and another costar on the show, Ron Rifkin, in New York City.
