Gorilla Grodd Shows Up At The Flash Grant Gustin's Birthday Party

When The Flash star Grant Gustin turned 25 today, the way to celebrate on set was perfectly clear:

There has to be a gorilla in a dress.

Luckily for all involved,The Flash has access to a gorilla suit -- one presumably used for shots of Gorilla Grodd, or perhaps as his stand-in for lighting and the like.

You can check out the Instagram post below that shows the cast of The Flash know how to party.

 

Happy Birthday to meeeeeee. Thanks everyone that has made me feel so special today. I don't deserve it and you're all so sweet. Thank you thank you.
