Taylor Swift has been hanging out with Haim a lot lately, and it looks like they'll be traveling together a bit more this year as the sisterly pop-rock trio are joining T-Swizzle on tour.

Announced yesterday via Twitter, Haim will be sharing the stage with the 'Blank Space' singer in seven cities including Chicago, Washington, D.C. and Nashville, with five different gigs in Los Angeles.

Swift and Haim have been spending a lot of time together recently, so she was more than excited to announce the additions to her tour. Vance Joy and Sam Mendes will also be part of this tour.

And Haim are pretty excited to join Tay Tay on tour, too.
