Taylor Swift's inner circle is a box of surprises when she shows up with Woody Allen and Mia Farrow's son

Taylor Swift includes Mia Farrow's son in her group of close friends as the 34-year-old popstar appeared in New York City to party with pals at the members-only club Chez Margaux on November 19.

The Eras Tour sensation headed to the joint along with Ronan Farrow, a journalist, who is the son of the Rosemary's Baby actress, Mia, whilst Faith Hill, Este Haim, and Woody Allen were also spotted there too.

An unlikely friendship on paper, the pair are strong friends and even shared an intimate greeting as they hugged when they saw each other before they dashed off to one of the private rooms where Hamer Morgenstern, Ronan's partner, joined them.

"Taylor and Ronan seem to be very close friends," an insider told PageSix.com. "They got excited, hugged, kissed, and she grabbed his hand and went to the private room with the others."

It's the second time the billionaire has been spotted with the Pulitzer Prize-winning reporter this November after they were also seen at the same club along with the Marvel Cinematic Universe's Zoe Kravitz, who also stars in James Cameron's Avatar franchise.

Woody Allen joins the club

Ronan may have appeared on the Fortnight singer's radar after using his platform to slam Harvey Weinstein and other sexual abusers in the Hollywood industry, including his own father, Woody when the director was accused of sexual misconduct by Mia in 1992.

The mother of their adopted daughter, Dylan, reported her husband to authorities after the seven-year-old said he touched her private parts whilst witnesses said she had no underwear on. After a consultation with the family's pediatrician, the matter was handed to investigators.

Farrow and Dylan were both accused of making the incident up, but this was rejected by Justice Elliott Wilk but the matter stopped being pursued when Mia decide she didn't want to add further trauma to the child, despite an attorney having "probable cause" for criminal action.

It's unclear if they happened across Allen during the time at the club, who remains free despite the allegations against his name, which he continues to deny.
