They first starred together in 2005's Sisterhood Of The Traveling Pants, before reuniting for the sequel in 2008.
And while it's been 12 years since the film's release, it seems Blake Lively, America Ferrera, Alexis Bledel, and Amber Tamblyn didn't just play best friends on screen - they are close pals in real life.
With talk of a third instalment in the works, Lively satiated the hunger of Traveling Pants fans and shared a snapshot to Instagram embracing her 'sisters.'
One key member, however, appeared to be absent from the photograph. So obviously Lively did what we'd all do and hit up Instagram's paintbrush to fix the problem. The actress drew a delightful stick figure with a heart head to step in for the Ugly Betty actress. You literally can't tell the difference.
The actress wrote: 'Divine Secrets of the Ya Ya. [America Ferrera] while professionally editing you into this photo, I realized you have the coolest and most appropriate initials EVER!" she wrote alongside the hashtags, 'badass AF' and "sisters forever."'
Ferrera replied to Lively's post, writing, 'Blake, you're like a professional portrait drawer. I was so confused about how I got into that pic! #goodateverything #loveyou.'
The picture is a throwback to earlier this year during the premiere of Tamblyn's directorial debut, Paint It Black, in May at The Museum of Modern Art in New York City, where her former co-stars joined her in support.
But it's a lovely reminder once again that actresses are truly good friends. Earlier this week, Ferrera reunited with Tamblyn, who introduced her 5-month-old baby girl, Marlow, with husband, David Cross to her best friend.
'The future is sisterhood,' she captioned the image of Ferrera kissing Marlow on the head.
We await the onscreen reunion, gals.
