my 6yr old daughtet wants to write to cher lloyd inviting her to her 7th bday party ?

is this even.possible ? this morning out of the blue my daughter asked if she can invite cher to her bday party. For the life of me I couldnt tell her no, so i've joined this group to see if there is a fan address at all ? because I can only but try for my little bopper. ?
thanks
