Taylor Swift, Calvin Harris Double Date With Ex Joe Jonas & Gigi Hadid [PIC]

It looks like Taylor Swift and Joe Jonas have come a long way since the former Jonas Brother broke up with the 1989 singer over a 27-second voice mail. I mean, she even wrote "Forever and Always" from her Fearless album about the split from the teen heartthrob. However, she is proving that there is no bad blood between her and her ex, as they went on a date together over the weekend. Don't get any ideas though -- Swift isn't ditching her Scottish DJ boyfriend Calvin Harris to give Joe another chance. Instead, Tay and Calvin went on a double date together with Joe and model Gigi Hadid.

The pals took in the sights of London and Swift took to her Instagram to post a cute little photo of the four friends with their boat captain, Karlie Kloss. In the photo, the five-some posed on the River Thames in London in front of Tower Bridge as they sped down the famous waterway.

Swift and Harris couldn't keep their hands off each other in the snap, as the singer had her arms wrapper around the DJ's neck while Joe and Gigi get close to one another on the other side of the boat. Meanwhile, Karlie stands in front of the two couples with a huge grin on her face.

Taylor captioned the picture, "Little known fact: Karlie is secretly an unofficial historian/London tour guide. Kind of."

Us Weekly also reported that Joe and Taylor broke bread together earlier this month as they had lunch together at Plan Check in Los Angeles with Joe's rumored girlfriend, Gigi Hadid.

These two have definitely come a long way since their breakup back in 2008.
