Taylor Swift And Lorde Have Girls-Only Weekend: See The Pics

The singers go shopping in Cali like BFFs.

It looks like Taylor Swift and Lorde are on the fast track to becoming BFF's.

The two pop stars were seen out-and-about in Los Angeles enjoying a girls-only weekend. On Saturday, Swift posted on her Instagram a shot of the two of them casually dressed at the beach with their "bare feet in the sand."

The following day, the girls traded in their beachwear for their Sunday best as they spent some time shopping together at Rag & Bone and Free People in West Hollywood, California.

No word if the two singing stars stopped by a recording studio during their weekend together, since Lorde recently told Capital FM Radio that she would be willing to collaborate with her newfound friend.

"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," Lorde said. "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."

Swift and Lorde have been spending a lot of time together over the past few months. The "Royals" singer was one of the guests at Swift's recent Australian garden party to celebrate her 24th birthday in December.

The following month, the two cheered each other on at the Grammy Awards, where Lorde took home two trophies, including one for Song of the Year.

During the night, the singers both took the stage, posed for the cameras, hugged in front of the A-list audience and let everyone know that they are "on each other's team."
