Blake Lively has a lot going on this week—She’s Vogue’s August cover girl, she’s got a viral video on her hands, AND she launched her brand spankin’ new Goop-ish website, Preserve. So for today’s #FirstFriday, we’re taking a look back at Blake’s early years in the biz—specifically her first huge premiere, for The Sisterhood of the Traveling Pants in 2005. And what a premiere it was…

Before she was Blake Lively: Vogue Cover Girl, she was Blake Lively: Adorable Budding Fashionista

Here she is, hamming it up for the cameras with her hottie co-star, Mike Vogel.

And with the always adorable Alexis Bledel and Bradley Whitford (who played America Ferrera's dad in the film)

Non-stop ham with Ferrera and Amber Tambyln.

But while all eyes were on the four main actresses in 2005—today, it's all about the other stars who walked the red carpet…

Like Ashley Tisdale, for example.

And Shia Labeouf! Oh dear, sweet, pre-weirdo Shia Labeouf.

And you remember the Cheetah Girls right? That’s our gal pal Adrienne Bailon on the left!

Victoria Justice was so teeny-tiny in 2005!

And Emma Roberts was just 14-years-old! Thought the spaghetti-straps probably gave that away.

YES! YES! YES! YES! Yes, Taylor Lautner, Yes.

And just for funsies—This is what Hollywood “it” girls wore in 2005...

AND THIS.
