Taylor Swift, one of Blake Lively's closest and most famous friends, is now involved in the notorious case between Lively and Justin Baldoni. New documentation supplied by Baldoni's legal team alleges that Lively relied on her celebrity friends and connections to make sure her version of the film "It Ends With Us" was the one that made it to the final cut version of the film.

Justin Baldoni has made a claim about Taylor Swift in his new lawsuit against It Ends With Us co-star Blake Lively.

While Taylor Swift is close enough to both Blake Lively and Ryan Reynolds to have been named their daughters' godmother, she's far from their only famous friend. However, that's not the only reason many are assuming Swift is the celebrity friend in question.
