Nicole Kidman has been upstaged -- by Zac Efron's bulging biceps!
The two were both spotted on the set of their upcoming flick "Paperboy" this weekend in L.A., where Efron showed off his tickets to the gun show in a black tank top.
While Efron attracted some serious attention, Kidman was barely recognizable while wearing a blonde wig and animal print top.
The movie is based on the book of the same name and also co-stars Matthew McConaughy and John Cusack.
