Taylor Swift doesn't get many nights to herself, since she presides over a multi-million dollar musical empire and is currently on tour. Understandably, she's in high demand. But when the 23-year-old superstar does enjoy the rare night off, she makes sure to have a little fun. Literally.

Swift and her pals Dianna Agron of 'Glee' and Sarah Hyland of 'Modern Family' took in a fun. show at the Greek in Los Angeles on Wednesday night (Sept. 4).

The ladies sang along to the band from side stage, with Swift looking cute in her floppy black hat, making the best of the time she had away from work. Swift retweeted a Vine video of herself and her gal pals goofing off at the show.

She also tweeted her excitement to take in a concert that wasn't her own. "Watching @OurNameIsFun live tonight at the Greek was unforgettable," the 'Red' star wrote. "Such incredible musicians and showmen. It was just SO good."

Anyone else think this might lead to a fun. guest spot on an upcoming date of the 2013 Red Tour? You never know. Swift opens her arms wide for fellow artists at her shows, having recently sung with Carly Simon and Sara Bareilles, among others.

She'll resume her own Red Tour on Sept. 6 in Fargo, N.D. We are glad she enjoyed her day and night off in a productive way!
