Carrie Underwood began appearing this year in a series of Vitamin Water commercials, and the latest features an odd mix of music and sports stars. In addition to Carrie, it includes rapper 50 Cent, Boston Red Sox baseball star David Ortiz and Chicago Bears football player Brian Urlacher.As it turns out, Carrie and 50 Cent β€” a.k.a. Curtis Jackson β€” became buddies on the set.

“He was joking around with me,” she told Dial-Global. “I was the only girl there, so I felt kind of uncomfortable, and I was like a midget next to all these, like, giant guys. So, yeah he was trying to make me feel at ease, and he’s a really cool guy. I feel very sad that his house recently burned down, so I hope he can figure all that mess out.” Carrie, David, Brian and 50 Cent make quite a foursome, and so do Karen Fairchild, Jimi Westbrook, Phillip Sweet and Kimberly Schlapman. They’re better known as Little Big Town, and they’ll be opening for Carrie when she launches her next major tour in the fall.
