How can you put in the redeem code on Movie Star Planet

Click on "Become VIP" on the right up in the corner OR go below on the left side corner below and click on "Diamond VIP" and then click "Redeem Code". Type in the code you get in the Email that MSP should've sent to you and type in that code. Then click on the Blue "redeem code" button again. Congrats! You are now a VIP.
