Actor Chris Pratt on Wednesday apologized for posting a photo on Instagram of him posing at a gym with a single-use plastic water bottle in his hand after “Aquaman” star Jason Momoa called out his fellow Hollywood star.

Pratt posted the Instagram photo on Tuesday as part of a collaboration with Amazon.

This prompted Momoa to comment under “The Guardians of the Galaxy” star’s photo saying, “Bro i love you but wtf on the water bottle. no single use plastic. come on.”

Pratt apologized in response saying, "Aquaman! You’re completely right. Dammit. I always carry my big gallon size reusable water jug with me too. I even had it that day!!!"

"Love you too buddy,” Pratt added in his reply. “My bad. I don't want your home of Atlantis covered in plastic. Hear that kids? Reduce. Reuse. Recycle."

Momoa then posted his own Instagram photo of himself and his children with Pratt apologizing for how his comment came across.

“I’m sorry this was received so badly today I didn’t mean for that to happen,” he wrote. “I’m just very passionate about this single use plastic epidemic. the plastic water bottles have to stop i hope u make a reusable water bottle for amazon so we all can purchase.”

The “Game of Thrones” actor has been an active promoter of environmental activism throughout his career, including speaking at a United Nations Small Islands event in October, according to USA Today.
