While Katy Perry, Keri Hilson and Jennifer Nettles were channeling WWII pinup gals in their promo pics for VH1 Divas Salute The Troops, the trio seemed to be channeling the Andrews Sisters for the show’s rehearsal last night (should we expect a rendition of “Boogie Woogie Bugle Boy”). The concert event (hosted by D-list diva Kathy Griffin) airs this Sunday, December 5 at 9pm and will also include performances by “Right Thru Me” rapper Nicki Minaj and CMT presenter Hayley Williams.
