Taylor Swift and Calvin Harris Go On Double Date with Joe Jonas and Gigi Hadid, Karlie Kloss Fifth Wheels! [PHOTOS]

Maybe this is Joe Jonas' way of debunking those dating rumors with Karlie Kloss. On a boat ride in London this weekend, the 25-year-old Jonas brother hung out with Gigi Hadid as they joined Taylor Swift and Calvin Harris for a double date. Tay's best friend Karlie Kloss also joined the foursome on Sunday.

Taylor revealed the romantic getaway with Calvin Harris, Karlie Kloss, Gigi Hadid, and ex-boyfriend Joe Jonas on Instagram. As the five-part group passed one of London's most breathtaking landmarks, the couples with Karlie Kloss lovinginly smiled for the camera.

Calvin Harris' girl Taylor Swift captioned the photo, "Little known fact: Karlie is secretly an unofficial historian/London tour guide. Kind of."

However, it seems as though Joe Jonas was looking to hide the fact that Taylor Swift and Calvin Harris was present at the latest excursion. The "Camp Rock" actor shared some snaps of the boat ride on his Instagram too.

However, the photos leave any evidence of Taylor Swift and Calvin Harris actually being there. But the outfits are distinctly similar to the ones they wore in the Taylor Swift photo.

First, Jonas shared a snap of himself opening a bottle of champagne or wine. He wrote in the caption, "#IMONABOAT," referencing the song popularized by The Lonely Island featuring T-Pain for a "Saturday Night Live" segment.

Captioned with an emoji of the UK flag, Joe Jonas shared a beautiful and seemingly candid shot of Hadid aboard a boat, and with Big Ben as its background.

Jonas was infamous for dating Swift back in 2008. A few years later, in 2011, rumors started floating that Joe Jonas was dating Karlie Kloss after the two made an appearance together at a polo match in Santa Barbara, California.

Since then, Kloss has denied the rumors, stating that she and Nick Jonas' older brother are just "great friends."

It's nice to see the exes bury the hatchet, even after a horrible breakup through a "27-second" phone call. In fact, this is the first time that exes Taylor Swift and Joe Jonas hung out with their other halves.

Taylor Swift once joined Jonas and Gigi Hadid at the Plan Check in Los Angeles. Reports claim that Harris was present with the rest of the group earlier the same day at Jamie King's baby shower.
