Pop superstar Taylor Swift has reportedly ended her long-standing friendship with actress Blake Lively, expressing regret over their association following a legal dispute involving Lively and director Justin Baldoni. Sources close to Swift indicate that she feels "used" after being inadvertently drawn into the $400 million lawsuit filed by Baldoni against Lively and her husband, Ryan Reynolds.

The lawsuit alleges that Lively and Reynolds leveraged Swift's celebrity status to influence creative decisions on the film adaptation of It Ends With Us. Although Swift's team has denied her involvement in the film's production, citing her commitments to the Eras Tour during its filming, the association has reportedly strained her relationship with Lively. 

In a significant move, Swift's boyfriend, NFL star Travis Kelce, has unfollowed Reynolds on social media, signaling support for Swift amid the controversy.

Despite a recent attempt by Lively to mend their friendship, offering a personal apology to Swift, the damage appears to be irreparable. An insider revealed that Swift "wishes she never met Blake," underscoring the depth of the rift between the former friends.
