John Legend has nothing but good words for U.S. President Barack Obama and his wife Michelle.

While promoting the upcoming film “Southside With You,” which tells the story of Barack and Michelle’s first date, Legend gushed about how cool the power couple is in person.

"I've been around both of them quite a bit and I think they are just so cool," Legend told People during a recent press conference for the movie at The London Hotel in West Hollywood, Calif. "We are so fortunate to have two people who are so brilliant, so authentic, so honest and full of integrity and who have a true love for each other and create this beautiful partnership together as the representative couple of America."

When asked what exactly makes the pair “so cool,” Legend, who executive produced the film, said that it is their humility. "What's so cool about them to me is that, with all this power, with all this grandeur that surrounds the office they're still really down to Earth," the “All of Me” hitmaker explained. "They still are really in touch with the people and still so relatable and I think that comes from the fact that they know where they come from and know where they met."

"I think they still carry that with them everywhere they go and I think it gives them perspective," added Legend, who also wrote the song "Start" for the film’s soundtrack. "Whether they're in the White House or hanging out with their friends or wherever they are, they're authentic and that's what I think about the President and First Lady."

According to Deadline, “Southside With You” chronicles the summer 1989 afternoon when the future U.S. president wooed his future first lady on an epic first date across Chicago’s South Side. Written and directed by Richard Tanner, the film stars Parker Sawyers as Barack and Tika Sumpter as Michelle.

The movie had its world premiere at the Sundance Film Festival this past January, and shortly after that, Miramax and Roadside Attractions acquired distribution rights to the film, Variety reported.

“Southside With You” opens in theaters on Aug. 26.
