If you want to get your photo taken with Miranda Lambert, it may cost you 100 bucks.

Miranda is charging fans $100 to pose for a photo at her Oklahoma store, The Pink Pistol . . . but she's donating the cash to her favorite charity Mutt Nation.

According to Miranda, "I'm constantly moving merchandise and working, and if I get stopped and asked for a picture, it'd go crazy. Now I can do pictures and meet fans and also raise money for my doggies. So it works out good."

To date, Miranda has already raised $2500.00 for the cause.  Good for you Miranda.  Good for you.  She also has some cool T-shirts available on the must nation web site.  Click here to find out more.
