When you're a teenager, or even a pre-teenager, there's things you were interested in or excited about that'd undoubtedly make the older version of yourself more than a little embarrassed.

In some cases, it can be a goth phase (guilty) or it can be turning up at a Spice Girls concert dressed as Baby Spice, Emma Bunton. So it went for Blake Lively, but the story of how this information came to light is even funnier.

A random photograph from Twitter user Bria Madrid explained that she had a photo taken with a random girl at a Spice Girls concert at the Glen Helen Amphitheater in San Bernadino, California in 1997 who was cosplaying as Baby Spice - which, unbelievably, turned out to be none other than Blake Lively.

And, sure enough, Lively was mature enough to cop to the fact that, yes, she was a huge Spice Girls fan back in the day and was even willing to dress up like them.

That said, the real Emma Bunton hasn't responded yet and seeing as how there's been constant chatter about a possible Spice Girls reunion, Blake Lively's probably lacing up her platform shoes for just such an occasion.
