With all the artists Taylor Swift's managing to bring out for her shows during her American Speak Now tour, we'd be a bit disappointed if we were in the audience and we just got exactly what we paid for - all Taylor, all the time.
Her latest addition to her celeb-duets is Mr B.o.B, who she brought on stage with her Dallas to sing Airplanes, the single he released with Paramore's Hayley Williams
"Tonight was like a dream. That crowd.. The biggest indoor stadium in the world. And singing 'Airplanes' with B.O.B. !!!!! (@bobatl)," tweeted The Swiftzer after the show.
B.o.B was at his keyboard to, saying he "Had a night to remember in Dallas performing one of my biggest songs with the ever-so enchanting @taylorswift13"
"You know how kind it was of you to make this show at Cowboy Stadium a sold out show on a Saturday night?" Taylor asked the crowd at the gig.
"So kind in fact, I thought I might bring along a guest if that's ok with you..."
