It's a girl's day out for Taylor Swift and Lorde, who were seen hanging out last Sunday in New York City. The BFFs spent their afternoon hanging out in a park wearing black ensembles. The 24-year old country singer was spotted wearing a black peacoat matched with a pair of maroon skinny jeans. The 17-year old pop star, on the other hand, looked like a goth chic wearing a long black coat.

The press people had fun taking photographs of Taylor Swift and Lorde, who also enjoyed doing silly poses for the paparazzis. The besties were last seen together in Malibu almost a month ago. The Pennsylvania-born singer even posted photos of her and the New Zealander having fun at the beach on her Instagram account. Her photo caption was "Bare feet in the sand on a Sunday."

Did Lorde really get out of her way to be with her new BFF? Reports revealed that the Kiwi singer will be having a series of concerts at the Roseland Ballroom. Most probably, Taylor will be there to support her best friend.

The fans of the hitmakers are all wondering if the two will collaborate on music someday. Do you think that the Roseland Ballroom will be the venue for that since there is a possibility that Taylor will be watching Lorde?

During an interview with Capital FM radio, the 'Royals' singer revealed a potential duet with her bestie. She said, "Yeah we are different, but I think the cool thing about Taylor is she is pretty willing to go a lot of places with music."

The singing sensation also added, "I think that last record [Red] in particular, everyone was like 'Woah', a lot of ground has been covered." She added, "And I think with an artist like her, the sky is the limit."
