Where online can I find cheap meet-and-greet passes for Rihanna concert? Help me!?

I've bought 2 balcony level tickets from ticketmasters but I don't know for sure if they come with a meet and greet pass to get a photo taken with Rihanna. Her concert is on June 25th. I've tried searching for passes that are cheap but all I could find is tickets only that come with meet and greet for $700 dollars each with 2 together which is ridiculous! Why would I pay such a high amount just to meet one performer!? Anyone who pays that high of a price to meet and greet Rihanna is crazy. I've even looked at Rihanna's facebook page and seen pictures of her and fans! I want to have a picture taken with her! I even see 10 year old kids that have gotten their photo taken with her. How do they do it? And which website do you get these passes from that are cheap? Help me please! It will be much appreciated!
