So what if old Hollywood movies make Jennifer Garner tear up a little?! While recently attending the screening for The Sound of Music at The Hollywood Bowl in Los Angeles, the beloved actress gave her fans a glimpse inside her emotional — but totally adorable — moment.

“When your kid catches you misty-eyed at the Sound of Music sing-a-long,” the 47-year-old beauty hilariously captioned an Instagram video on Thursday, October 10. In the clip, Jen can be seen wiping tears from her eyes while simultaneously singing along to “Do-Re-Mi” by the film’s lead, Julie Andrews.

Along with her caption, the 13 Going on 30 star — who is the proud mom of Violet, 13, Seraphina, 11, and Samuel, 7, with ex-husband Ben Affleck — added the hilarious hashtags, “I don’t care” and “perfect night, perfect movie.” Aww!

Jen’s fans quickly flooded her comments with a similar affection for the iconic 1965 film. “I just sang that with you at the top of my lungs. My teenager thinks I’m crazy and I don’t care!” one fan gushed. Another echoed, “Beautiful! And what fun!”

As thousands of fans praised Jen for her incredible taste in movies, others noticed a comment from her pal Katie Couric. “I’m interviewing Julie next week!!!! Come with!!!” the former Today star wrote on Jen’s profile.

Although Jen has yet to respond to Katie’s invitation, fans couldn’t help but imagine what it’d be like to have those three ladies together in one room. “This would be magic! This needs to happen! The world deserves this moment!” one fan insisted. Another chimed in, begging, “You HAVE to go!!!!”

Despite the fact that Jen seemed like a hoot and a half at the L.A. screening, she previously dished that her kids don’t consider her the most entertaining. In fact, the mom of three joked that her one daughter even dubbed her the “fun-killing mom!”

“If you’re like me, I kill the fun,” Jen explained to Jimmy Fallon during her appearance on The Tonight Show in mid-September. “I am so lame. I say no to everything. They call me the dragon. They have all these names for me.” LOL!

By the looks of her display during The Sound of Music, we’d say Jen is the complete opposite of boring!
