Katharine McPhee & David Foster Help Their Friend Clive Davis Celebrate His 90th Birthday!

Katharine McPhee and David Foster are back on the red carpet for a good reason!

The married couple stepped out to attend Clive Davis’ 90th Birthday Celebration on Wednesday night (April 6) at Casa Cipriani in New York City.

David hosted the second half of the evening, which featured performances from stars like Barry Manilow (pictured in the gallery with Clive), Kenny G, Art Garfunkel, Dionne Warwick, and more.

Gayle King was at the event to interview Clive on stage for the first half of the event. Among the stars on the carpet was Sex and the City creator Candace Bushnell, who is pictured in the gallery.

The event was produced by Erich Bergen, who starred alongside Kat in Broadway’s Waitress, and Marc Johnston, who is David‘s longtime manager. They also executive produced the four-part series Clive Davis: Most Iconic Performances, which is streaming now on Paramount+.
