Johnny Depp is known for never blending into the background … but at a recent Vegas event, he literally started eating it.

While attending Drink Las Vegas — a four-day event across multiple hotels — at Park MGM last night, the “Pirates of the Caribbean” actor stopped to pose for photos … and, well … munch on some plants.

In the video obtained by TMZ … Johnny bit a leaf from the photo call’s backdrop before chewing on it in front of the event’s attendees.

Johnny seemed to be in good spirits … so it looks like he was just having a bit of fun with a few photographers!
