Hillary Clinton's presidential campaign is bringing out the big fundraising guns as the race for the White House enters its final three months. With time of the essence, the Clinton camp has tapped music legend and gay icon Barbra Streisand to headline an LGBT-focused New York campaign fundraiser on Sept. 9 at Cipriani Wall Street in New York, Billboard has confirmed.

Barbra Streisand Disses Trump, Promises Hillary-Led 'Happy Days' at Powerhouse L.A. Tour Opener

According to Buzzfeed, which first reported the news, the invite for the "LGBT for Hillary" event features a rainbow H logo and lists dinner ticket prices starting at $1,200 and ranging up to $250,000 per, with those who pony up six figures earning a meet-and-greet with the candidate.

Streisand has been firmly in Clinton's corner all year, defending the former Sec. of State against detractors who've criticized her high-dollar speeches in front of Wall Street bankers and hedge fund managers, and lashing out at Rep. candidate Donald Trump for his controversial statements. The New York show -- whose capacity has not been announced -- will benefit the Hillary Victory Fund, with money raised going to Hillary for America, the Democratic National Committee and state parties.

Her tour is slated to wrap up in Toronto on Aug. 23, giving her plenty of time to rest up for the Clinton fundraiser.
