Both sides in closing arguments Wednesday suggested a two-year suspended sentence for 28-year-old Nadja Benaissa, a member of German girl-band No Angels.
Benaissa acknowledged in the trial that she had unprotected sex despite knowing she was HIV-positive and says she made a big mistake.
German news agency DAPD reports the man who claims Benaissa infected him says they had a three-month relationship at the beginning of 2004.
A verdict is expected Thursday. The charge could carry several years in jail.
