There's no such thing as solo solo pictures at this premiere, just pictures where they've cropped the other person out. I guess it's a result of this:
It was big surprise for photographers and fans alike as the duo known as Zanessa - Zac Efron & Vanessa Hudgens - showed up to Russell Brand's film "Get Him To The Greek" also starring Jonah Hill. As the premiere seemed to peter out as Russell and Katy Perry walked the carpet, the photographers were ready to pack their bags and cameras when low and behold, Zac and Vanessa hopped out of black SUV. Zac and Nessa posed up a storm for the red carpet photogs. Overhead as they were interviewed by Entertainment Tonight, the twosome mentioned that they are big fans of Russell Brand. But a slight disappointment was Zac and Vanessa did not want to do solo shots.
