Katharine McPhee and her husband David Foster went back on stage two weeks after Yadira Calito, the nanny of their 2-year-old son Rennie, died.

Erich Bergen, who worked with Katharine McPhee in the movie Waitress, joined her onstage at a private event in Ravello, Italy, on Tuesday, August 22. In 2019, McPhee, who is 39, and Foster, who is 73, got married.

Bergen, who is 37 years old, shared clips from the event on Instagram on August 23.

“Singing Frankie Valli and The Four Seasons songs in Italy just seems appropriate. So great to perform with my friends @davidfoster @katharinefoster and @thelondonessentials,” he wrote in the description.

About two weeks before the show, McPhee said that she and Foster would not be going to the last two Asian tour shows because of a “horrible tragedy” in their family.

On August 11, the singer wrote on Instagram, “At least one of us needs to get back home to our family.” Foster kept going with the last two shows, which were on August 11 and 12 in Jakarta.
