Backstreet Boy: 'Swine flu was scary'

Brian Littrell has admitted that having swine flu scared him.

The Backstreet Boys member was diagnosed with the illness last week and was forced to cancel promotional appearances.

However, In Touch reports that the singer has now returned to work.

"I was pretty freaked out," Littrell said. "We had to cancel a bunch of press. It was disappointing."

The other members of the band were prescribed Tamiflu as a preventative measure and kept their distance from Littrell.

"I had to stay in New York and was confined to my hotel room," he explained. "They all left me and went to LA. I was like, 'Thanks guys, appreciate it!'"
