Former Morning Musume member Ishiguro Aya (25) admitted on a live TBS program yesterday that she is five months pregnant. Appearing daily on the show this week, rumors spread about the reason for her extended belly before show host Isono Kiriko (40) finally asked her straight. She is already the mother of two girls with her husband, former Luna Sea drummer Shinya (34), who is currently working as an artist. Ishiguro quit the hugely popular group three years ago.
