Bruno Mars called into the show to talk about his upcoming tour, his four beautiful sisters on a new reality show and more!

Bruno called the show from London to promote his new album "Unorthodox" and said he can't wait for his tour, which hits Houston, Texas on March 7, to kick off.

"I haven't gone on tour in over a year," Mars said. "It's going to be nice to get with the band again and do what we do."

Mars also talked about his sisters' reality show, which is set to air on WE TV and follows the four as they move from Hawaii to Hollywood.
