Music icon Lady Gaga is the latest American celebrity to weigh in on the presidential election, accusing candidate Donald Trump’s wife of being a hypocrite for her anti-bullying stance.

Lady Gaga, whose real name is Stefani Germanotta, took aim at Melania Trump on Twitter after the First Lady hopeful delivered a speech last week vowing to fight cyber bullying if her husband is elected.

“[T]o say u will stand for “anti-bullying” is hypocrisy,” Lady Gaga, who has changed her name on Twitter to “#VoteHillary”, tweeted at Ms Trump.

“Your husband is 1 of the most notorious bullies we have ever witnessed.”

During a November 4 rally in Cleveland, Ohio, music power couple Jay Z and Beyonce threw their support behind Ms Clinton.

“This other guy, I don’t have any ill will … he cannot be my president,” Jay Z said of Mr Trump.

“He cannot be our president. Once you divide us, you weaken us. We are stronger together.”
