If you tried that and the balloons aren't showing up for you today, I'm wishing you a happy birthday and encourage you to watch this hour-long animation of sweet little balloons to celebrate.

A separate star-shaped gold balloon contained only the young royal's name, while a second white one was decorated with the words 'Happy Birthday' in bold colors.

A mylar balloon has a metallic coating. You can find them in most stores with words such as ‘Happy Birthday’, ‘Get Well Soon’, or in this case ‘Happy Valentine’s Day’ written on it.
