Taylor Swift worried about THIS ex attending her wedding

Zoe Kravitz, who is close friends with Taylor Swift, is allegedly dating her best friend's ex, Harry Styles.

It looks like the 35-year-old singer is is deep trouble due to her friend being in a relationship with her ex.

A source revealed drama stirring behind closed doors in a discussion with Closer magazine.

“Zoe is super chill, … it doesn’t seem to have crossed her mind that it might be uncomfortable for Taylor and Travis.” The tipper said.

The possibility of having to invite an ex, whom the singer likes to avoid at all costs behind the scenes, to her wedding is agitating her.

“Taylor swears up and down that she doesn't mind that Zoe is dating Harry, but she’s also not going to put herself, or Travis, in an uncomfortable position,” the insider continued.

“Everyone knows Taylor was obsessed with him and was left feeling pretty rejected, so seeing him with someone she considers a close friend has got to be more than a little strange.”

“It’s pretty natural that things between her and Zoe would get a little complicated.”
