The fun-loving pair posted a series of selfies on Kardashian's social media accounts on Wednesday to reveal that they were spending time together across the pond.

"London calling," Kardashian wrote on Instagram under a selfie taken by Lohan.

Clearly, the pair hit it off, as they did more than just post a measly selfie. The oldest Kardashian sister also took to her Snapchat account to share another picture of the new dynamic duo writing, "I found my long lost twin."

In their Snapchat selfie, the fast friends are rocking the flower crown filter with Kardashian wearing a little black dress and Lohan wearing an orange and blue striped ensemble. Peculiarly, Lohan's dress looks a lot like the fringey number Kardashian wore herself in a picture she had posted just hours earlier on Snapchat.

Did the pair switch dresses at some point in the evening? All signs would point to "yes!"

Here's to hoping that the "Keeping Up With The Kardashians" cameras were there to document the pair's every move.
