Taylor Swift Takes Boat Ride Through London With The New Brat Pack — Including Joe Jonas! [Video]

Taylor Swift is having fun in London, where she arrived to perform at the British Summertime Festival, as evidenced by a pic she shared with her fans on her Twitter account — and look who’s with her. Swift was joined by her rumored new man, Calvin Harris, and her friends, Gigi Hadid and Karlie Kloss — and her ex, Joe Jonas. Joe Jonas is rumored to be dating Gigi. The impromptu double date, with Kloss as a fifth wheel, enjoyed a boat ride through London in a break from Swift’s tour.

Taylor Swift and Joe Jonas famously dated back in 2008, reports ABC News. Taylor also tweeted “Little known fact: Karlie is secretly an unofficial historian/London tour guide. Kind of,” on her Twitter page.

It was rumored that Joe Jonas and Kloss were dating when, in 2011, they attended a polo match together in Santa Barbara, California, according to Entertainment Tonight. Kloss denied that she dated Jonas, but has said in interviews that she’s “great friends” with Joe. It seems confirmed now, given Taylor’s pic where Jonas seems cozy with Gigi Hadid, that Kloss is no longer dating Joe.

Swift made news in Dublin, after giving a sold out concert, because the “singer has insisted all photographers covering her live shows sign contracts which outline restrictions on what they can and cannot do with pictures of the pop star onstage,” making it more difficult for publications like The Irish Times to publish photos of the singer.

Taylor was joined online by a cast of A-list friends, including Serena Williams, who was in London to try to snag a sixth Wimbledon title, and Kylie Jenner, who’s reportedly good friends with Swift. Lauren Aquilina was there too, and posted a group snap on Twitter, writing, “spent tonight surrounded by bada** girls and couldn’t be happier about it.”

The boat tour wasn’t the first time Swift and Joe Jonas have been seen together with their respective better halves. Earlier this month, Swift joined Jonas and Hadid at Plan Check in Los Angeles. Entertainment Tonight reports that the group has been seen together at West Hollywood’s SoHo House, attending Jaime King’s shower.

The world is wondering if the group, comprised of Taylor Swift, Calvin Harris, Gigi Hadid, Joe Jonas, and Karlie Kloss, are the new “brat pack,” referencing the 1985 movie, The Breakfast Club. The stars of that movie were dubbed “The Brat Pack.” The jury’s still out, since it seems these kids switch partners a lot.
