In our rush to anoint a new celebrity diva with every turn of the moon, perhaps we’d be wise to remember the reigning diva has not relinquished her crown. There is no diva more deserving of the title than Liza Minnelli, a superstar by any measure. A winner of an Oscar, Tony, Grammy, Emmy and many other honors, Minnelli brings her act to Portland for a show at 7:30 p.m. Wednesday at Merrill Auditorium, presented by Portland Ovations.

Minnelli, 64, releases her latest CD, “Confessions,” this week. It’s a collection of timeless pop songs. She’ll perform material from the new CD as well as songs from throughout her career at Wednesday’s concert, accompanied by a jazz sextet.

Tickets cost $50, $75 and $125 through PortTix, the Merrill box office; 842-0800 or
