Here's yet another reason why we love Taylor Swift -- she loves rocking out during road trips!

Over the weekend the starlet posted a video of herself and the Haim sisters singing along to Faith Hill's "The Kiss" while on the road, and it looks like the ladies were having a blast celebrating Este's 29th birthday. Taylor, Este, Danielle and Alana have been spending quite a bit of time together, and it was recently announced that the ladies will be joining forces this summer for T. Swizzle's 1989 tour. Can't wait for that!
