Above, Streisand during her summer concert in Tel Aviv. Barbra Streisand proved she means business by collecting a check for a cool $2.3 million for singing at a banking conference at Lincoln Center on Friday, Confidenti@l has learned. The “Memory” singer was listed as the “surprise entertainment” at 2:45 p.m. on the schedule of investment firm Baron Funds’ 22nd Annual Baron Investment Conference at the Metropolitan Opera House.
She arrived under a cloak of secrecy in a black SUV with tinted windows that parked at the loading dock. And Babs got paid the whopping figure for what amounted to a miniconcert, one attendee says. She belted out 10 tunes, including “Memory,” “You Don’t Bring Me Flowers” and “People,” in just under an hour for the buttoned-up crowd. After her performance, she left just as stealthily as she arrived.
The audience was packed with more than 4,000 Baron shareholders, who arrived early in the morning for the all-day affair. Babs was the highlight of the event, which included presentations from business leaders and speeches by Baron Capital Group president Linda Martinson and CEO Ron Baron.
We hope none of them filmed Babs doing what she does best — she once threatened to sue former “Real Housewife of New York” Jill Zarin for taping her at a Friends of the Israeli Defense Forces fund-raising gala and posting the 30-second clip on YouTube.
Zarin was happy to take it down, tweeting, “Someone from Barbra Streisand’s company just called my store to tell me to take down my YouTube video or they will sue me. Is that nuts? Sorry guys. I took it down!”
Although Barbra was the queen bee at the conference, guests also heard numbers by the Counting Crows, Melissa Etheridge and Katharine McPhee.
While in New York, Barbra saw “Pippin” on Broadway and posed with Tovah Feldshuh and the rest of the cast after the show. Last night she picked up the 2013 Woman of the Year Lifetime Achievement Award from Glamour Magazine at Carnegie Hall.
Babs’ rep wouldn’t talk about the hefty paycheck.
“I have no idea, and if I did I wouldn’t tell you,” he said.
Baron Funds declined to comment.
