You know Oscar winner and overall legend Jennifer Lawrence.

Well, she attended Taylor Swift's record-breaking, legendary Eras Tour last night.

She's always been a big Taylor fan. She photobombed her at the Golden Globes in 2014.

She's praised Taylor in several interviews.

Taylor also wrote her Grammy-winning song "Safe & Sound" for Hunger Games, which Jen obvi starred in.

We've had few J. Law–T. Swift interactions during the past few years, but it was nice to see Jen supporting Taylor on tour.

But what I found most fascinating about Jen's attendance was the fact that she was spotted taking selfies with fans:

I just found it super interesting because Jen doesn't like taking selfies.

She told Vogue in 2017, "I’m happy to meet people, give autographs, shake hands, and say ‘Thank you.’ I wouldn’t have a job if people weren’t going to see my movies ... [but] if I’m on an airplane and I have no makeup on, I don’t want to take a selfie that’s going to end up on E!"

That same year, she opened up to Adam Sandler about disliking when fans approach her dinner table for a pic.

In 2018, she told USA Today that it became "too much." She told the reporter, "Sorry, I just see cellphones and I just [jump] ... Just while we’ve been sitting at this dinner, how many people have come up to me? Like five, six?"

But the Eras Tour has a way of changing people. She was taking selfies:

That's the power of the Eras Tour. That's all, bye!
