Spears is embarking on a month-long international tour, with Japan being its first stop. The pop superstar is also scheduled to perform in South Korea, Thailand, Hong Kong, the Philippines, Singapore and Israel.
And 23-year-old Asghari is there to support Spears during her time overseas. He tweeted the same video of the two dancing on Tuesday, adding that he came to Japan.
Meanwhile, 35-year-old Spears is keeping up her workout schedule even while on tour. Last week, she shared a video of her intense gym routine in Japan.
Clearly, Spears and her handsome boyfriend are showing no signs of slowing down. In March, the "Make Me" singer accompanied Asghari to support his sister, Fay, at Los Angeles Fashion Week, where she walked the runway.
