Jennifer Garner is reminiscing about just how funny Taylor Swift can be.

To celebrate Valentine’s Day, the Alias star, 51, shared a throwback video on Instagram of herself and the “Anti-Hero” singer, 34, during a scene from the 2010 film titled after the holiday.

In the video, Garner appears to be texting in an elevator as the doors open up to show Swift holding a large white teddy bear with a heart that reads “I love you.” As she steps in with the large bear, Garner can be heard saying, “Oh boy, oh boy.”

The pair share a greeting before Swift launches into some small talk. “So my boyfriend texted me this morning, and he was like ‘Look outside your door,’ ” to which Garner points to the bear and says ‘Oh.’ ”

“But you know I look outside my door and my boyfriend’s nowhere to be found, but there’s this giant white bear… on the ground,” Swift continues. “Yeah isn’t that the sweetest thing ever?,” Swift asks Garner who responds, “Ever and ever.”

The conversation between the two then turns hilariously awkward as the Grammy winner asks the actress, “Do you live here in this building because I see you in the lobby all the time, cause I live here,” to which Garner responds in a deadpan voice, “No, I just visit.”

 “Alright, I’m gonna go to school now. I’m gonna take my bear with me. Well, I hope you get a lot of Valentine’s today,” Swift says as the camera pans to the massive bear.

“Happy Anniversary to this sweet movie, Valentine’s Day. We miss you, Garry [Marshall]. 💕,” she captioned the video. She also hinted that she’d like to see the musician return to the screen, adding, “if @taylorswift is looking for something to keep busy, I’d like to remind her that she’s hilarious. 😂”

Valentine’s Day was one of Swift’s first forays into the movie realm after releasing her 2010 album Speak Now. She then followed it up with appearances in movies and TV shows such as The Giver, New Girl and Cats.

The film was directed by the late Marshall and had a star-studded cast, which also included Swift’s boyfriend at the time Taylor Lautner.

Anne Hathaway, Julia Roberts, Jamie Foxx, Jessica Alba, Bradley Cooper and many more also starred in the film about different couples spending the holiday together.

Swift detailed how she got the part in one interview saying, “I got a phone call from Gary Marshall saying, ‘Taylor, I want to have lunch or breakfast with you. I really want you to be in this movie. Will you let me write a part for you,’ and I could not believe it.”

“I couldn’t believe it because I didn’t have the time to be a big role in this movie. Gary was going to write in a small role for me,” she added. “It blew my mind.”
