During her Barclays Center Show in Brooklyn on Thursday night, Barbra Streisand took a shot at Donald Trump, the Republican nominee for president.

According to Page Six, Streisand quipped, “That's why we shouldn't vote for someone who believes climate change is a hoax,” before singing Pure Imagination.

Among those attending the show were Ralph Lauren, Donna Karan, Robin Roberts, Clive Davis, Gayle King, Sandy Gallin, Allen Grubman and Rosie O'Donnell, whose public feud with Trump goes back 10 years.

The outlet added that Streisand reminded the crowd that she had previously performed Happy Days Are Here Again for presidents Bill Clinton and Barack Obama before saying that she “was looking forward to singing it for Hillary as the first female president.”
