Jason Momoa Checked Chris Pratt for Holding Bottle of Water in IG Ad

Turns out Jason Momoa takes his role as “Protector of the Seas” pretty seriously.

The Aquaman star had a few words for Chris Pratt, who posted an Instagram ad of himself working out for Amazon. “You’re probably wondering why I’m standing here, low key flexing, gazing into the distance,” The Guardians of the Galaxy star wrote Tuesday. “Well, turns out I’m teaming up with Amazon to show you guys everything I use for my workouts, keeping active, and all that fun stuff to get you prepped for 2020.”

 Momoa took exception with the post, not because he has a problem with Amazon, but because of the plastic water bottle Pratt is holding in the picture.

“Bro I love u but wtf on the water bottle,” the actor wrote under Pratt’s post. “No single use plastic. Come on.”

Momoa isn’t new to this. Back in April, the Game of Thrones actor shaved off his beard in an effort to raise awareness about recycling and the environment. He also once refused to shoot Aquaman 2 in protest of a construction project that was happening on Hawaii’s tallest mountain in August.
