Crooner Shawn Stockman, of the legendary R&B group Boyz II Men, has been diagnosed with the H1N1 virus, fellow group members Wanya Morris and Nathan Morris told CNN News on Tuesday.

Stockman was unable to travel to Atlanta for a scheduled performance at the 2009 Soul Train Awards this week. Wanya and Nathan Morris are still planning to perform at the awards show.

“We tour eight months out of the year, and we are always traveling around,” Nathan explained. “It’s hectic for us always being in airplanes and airports. He got sick, and it hit him pretty hard. We go all over the world really, so I am surprised it hasn’t happened earlier, to be honest,” he added. “I talked to [Stockman] today, and he is doing much better.”

Shawn joins a growing list of stars who have fallen ill with swine flu, including the Backstreet Boys’ Brian Littrell, shock rocker Marilyn Manson, and Harry Potter star Rupert Grint.

The Grammy-winning, platinum-selling group has a new album coming out this month called Love.

R&B crooners Boyz II Men have been making the rounds on a promotional tour for their new LP.
