Gwyneth Paltrow Kiss With Stella McCartney Kicks Off GOOP Collaboration (VIDEO)

First she teased us with a cryptic announcement, then she gave us a little more to work with and now she's gone and taken the lid off the whole darn thing.

We're talking, of course, about Gwyneth Paltrow and her collaboration with designer bestie Stella McCartney. The actress has teamed up with the Brit for a line of clothing and accessories sold exclusively on GOOP, Paltrow's lifestyle site. But the touche finale of the exciting project has to be the video of the launch party the actress posted along with her GOOP announcement, which features Paltrow planting a friendly kiss on her so-called "sister" McCartney.

Providing us plebeians with an inside look into the celebratory English Garden Party in the Hamptons, the video features a bevy of A-list celebrity cameos, from Sarah Jessica Parker to Cameron Diaz to Paul McCartney. Between the lawn games and the yummy snacks, we can honestly say that this is one garden party we would've liked to crash.

Watch the video above!

Gwyneth has had quite the fashion journey:
