Little Big Town's Kimberly Schlapman and Karen Fairchild admit that they had a ball as hosts of the ABC special "CMA Music Festival: Country's Night To Rock," which airs tonight at ABC at 8pm ET. Thing is? They also admit that they didn't exactly act like professionals in interviewing Tim McGraw - so much that they aren't even sure about the network will - or even if - they'll use it!

What happened? All the ladies will say is that their interview with Tim included measuring his body fat.  While bandmate Jimi Westbrook accuses them of "abusing your power," the women explain that they got the idea from Tim's wife, Faith Hill.

See what all the fun was about during the three-hour special, which features interviews and highlights from this year's CMA Music Festival, which took place in Nashville back in June.  Besides Faith and Tim; and Little Big Town, the extensive lineup for the special includes Luke BryanEric Church (and Lzzy Hale - yay!) Florida Georgia LineMiranda LambertJake OwenBrad Paisley, and many more.
