The Aquaman star proved he really does care about our oceans when he encouraged Pratt to ditch his single-use plastic for a reusable water bottle on Tuesday.
Pratt posted a photo of himself on Instagram with the bottle in question while at the gym just hours earlier, as he promoted his new partnership with products that he uses to work out. The snap -- which shows off Pratt's ripped arms -- earned praise from family and famous friends.
"Lookin ripped!" Pratt's brother-in-law, Patrick Schwarzenegger, wrote. The actor's wife, Katherine, commented with heart-eye emojis.
"Is that a picture of me? Oh, wait. No. No it is not me. Common mistake," Sean Hayes joked.
Then came Momoa's comment: "Bro i love u but wtf on the water bottle. no single use plastic. come on," he wrote.
Pratt replied, “Aquaman! You’re completely right. Dammit. I always carry my big gallon size reusable water jug around with me too. I even had it that day!!!”
"I’m really stoked at the fan base and what we did with the movie and just went into Warner Bros. and DC and said, ‘You know, I have some ideas,’” he shared. "And, they love them and James [Wan, the director] and everyone is like, ‘We’re all taking it in. We’re excited to do another one.'"
"There’s a lot more in store on so many more levels," Momoa promised. "There’s going to be a lot. It’s way bigger!”
