Janet Jackson's longterm boyfriend Jermaine Dupri has put the superstar's fans minds at rest - assuring them she has fully recovered after a bout of illness. The "Nasty" singer sparked concern for her health after she pulled out of a special appearance on Saturday Night Live last month after coming down with particularly bad case of bronchitis.

The R&B star's illness became so severe she admitted herself to a Los Angeles hospital, complaining to doctors about being short of breath.

But Dupri, 35, insists the singer is back and fighting fit, revealing to People.com that Jackson is in Japan concentrating on promotional duties for her latest musical offering Discipline.

He says, "She's 100-per cent better now. She was really sick. She had bronchitis. She's in Japan right now. She's better and doing all the promotion that she didn't get to do because she was sick when the album launched."
