On Twitter, Carroll added, \"Harry Styles saw my predicament, tapped me on the shoulder and said he could watch Oscar while I went in. What a guy.\"

The photo shows a rather amused-looking Styles as he holds on tight to the leash of Oscar, the yellow lab.

Carroll said he figured Styles was trustworthy given his squeaky-clean reputation as a member of One Direction.

“I could see him through the large restaurant windows while I was inside and he kept his eyes focused on Oscar the whole time, never looking at his phone,” Carroll told “GMA.” “Oscar, on the other hand, was his usual troublemaking self, pulling away in every direction. He just doesn’t know how to play it cool.”

After being bombarded with follow-up questions, Carroll revealed on Twitter that the encounter wasn't recent, but did kindly reveal the exact time, date and place the dogsitting incident took place.

“I came back out, thanked Harry and sheepishly asked for a photo, something I normally wouldn’t do, but I wanted some proof that it happened,” Carroll told “GMA.” “He happily obliged. There was no one around because it was so late. Pretty much just Oscar, Harry and me in an empty parking lot.\"

It wasn’t Oscar’s last celebrity encounter. Carroll said that he and his wife have witnessed their pup get smiles from the likes of Bob Odenkirk, Jenny Slate and Brad Pitt.

“If you want to meet celebrities or just cool people in general, I highly recommend getting a dog,” he said.
