A German court has found a girl-band singer guilty of causing bodily harm to an ex-boyfriend by having unprotected sex with him despite knowing she was infected with HIV but she won't spend any time in prison.

The Darmstadt administrative court handed 28-year-old Nadja Benaissa a two-year suspended sentence after finding the 'No Angels' band member guilty.

Benaissa helped her case during the nearly two-week trial by acknowledging she had unprotected sex despite knowing she was HIV-positive and saying it was a big mistake.

In an emotional statement she told the court she was "sorry from the bottom of my heart."

The man who claimed Benaissa infected him said they had a three-month relationship at the beginning of 2004.

The singer has also been ordered to serve 300 hours of community service.
