The 28-year-old actor shared a beach photo on Wednesday with his bottom half bound in sand and sculpted into a mythical fin. Possibly gal pal Britt Brousseau's doing? The actor made sure to tag Brousseau, 26, in the caption and also threw in a Little Mermaid hashtag for kicks.
"Nothing to see here. Just another merman on the beach," Eastwood wrote, looking comfy and casual with the sand-fin accessory.
Eastwood and Brousseau were first linked this past May, and – whatever their relationship status is – it looks like things are going swimmingly.
Although Eastwood joked, "#itsforarole #ipromise #characterstudy," he's actually in post-production for Fury, the anxiously awaited wartime flick costarring Shia LaBeouf and Brad Pitt.
Brousseau posted a matching shot of her own on Instagram along with the caption, "So what if I pretend I'm a mermaid every time I swim........ with my merman @scotteastwood."
