Baby Spice commented on Blake Lively's Instagram throwback and she Lost. Her. Mind.

Blake Lively is a Spice Girls fangirl just like us.

The actress published a throwback photo on Instagram of herself dressed as Baby Spice at a Spice Girls concert in 1997, sporting Baby’s signature pigtails and a pair of incredible platform shoes.

Blake discovered the photo, in which she poses with a young Bria Madrid, after Bria posted the photo on Twitter.

“Found a picture when I was 5 at my first concert. #SpiceGirls and took a picture with a girl dressed up as Baby Spice who I just realized now was @blakelively,” Bria wrote.

Blake saw the Tweet and responded saying “My secret is out…” before uploading the photo to Instagram.

“Pretending to be someone else… since 1997 (Thanks @briaaamadrid for the photo of us at the Spice Girls concert. Sorry -not sorry- I tricked you into thinking I was @emmaleebunton)” Blake captioned her post.

She even tagged herself as Emma Bunton. Then the magic happened.

Emma, yes, the real Baby Spice commented: “So cute, you’re rocking those pigtails @blakelively.”

Blake lost. The. Plot.

“@emmaleebunton I’m officially ☠️☠️☠️☠️,” she wrote back. “Forever bowing down to you. ???????????? I cannot believe you know who I am. This will never be normal. ☠️????.”

Spice up your life. #CommentsByCelebs
