Britney Spears Channeled "That Girl" in Justin Timberlake's "Cry Me a River" Video

Oops ... She did it again. Britney Spears is referencing her ex Justin Timberlake again, and this time she's throwing some shade.

On Wednesday night, the "Toxic" singer posted a video montage to Instagram showing off an array of different outfits. And if one of them looks familiar, well you're not the only one to notice. Spears called out the outfit with the pageboy cap and said what we were all thinking: "Hmmmm something looks familiar …. The hat 👒 …. wait I look 👀 like that girl in the Justin Timberlake video with that hat in Cry Me A River !!!," she wrote in the caption of the video.

The particular outfit she's referring to included a black lace shirt and a tight white pencil skirt that she paired with black booties and a gray pageboy cap, similar to the one she wore to the Crossroads premiere in 2002 alongside Timberlake (and the one that was then later seen in Timberlake's music video for "Cry Me a River").

"Oh shit that's ME !!!," she continued. "I'm Britney Spears ⭐️ ??? I guess I forget that sometimes 🙊 😂 🤷🏼‍♀️ …"

Timberlake's "Cry Me a River" song and video were released in 2002, shortly after the couple's split (and after she wore the cap). According to Entertainment Tonight, he finally admitted that the song was about Spears in 2011 after initially denying it.

Spears also commented on the video in a 2011 interview with Rolling Stone.

"He called me up and behind it was, 'And by the way, you're in a video that's coming out. Don't worry about it. It's not a big deal,'" she explained at the time. "So the record label called and said, 'If you want to change this, you can.' I had the power to say no to the video. But I didn't, because I thought, 'Hey, it's your video.'"

She continued, "I hadn't seen it. Then it came out, and I said, 'I should've freakin' said no to this s**t!' I was so like, 'Woah. What is going on right now?' I think it looks like such a desperate attempt, personally. But that was a great way to sell the record. He's smart. Smart guy."
