“2017 been treatin me right,” Jack captioned one pic.

On another, he wrote, “mad walked by.”

He’s of course referring to his longtime girlfriend, Madison Beer, who’s on the trip with him.

Right before the New Year, Jack was spotted sweeping Madison off her feet and going into the ocean with her. Too cute!
