Marc Anthony used the early moments of UNIDO2 Las Vegas concert before a crowd of about 12,000 to again berate leading Republican presidential candidate Donald Trump over his tough stance immigration policies.

Billboard reports before launching into one of his many bilingual hits Anthony teased the crowd, "I've got a good one. It's simple, bilingual, so for those who don't speak Spanish, you can sing it in English. Even that son of a b*tch Donald Trump will get in."

Anthony went on to fire up the Mandalay Bay Arena crowd with talk of Hispanics here in the U.S. remaining united, no matter what part of the world they originated from.

"We're Latinos, no matter where you come from," he said. "In my country they call me Puerto Rican. In your country they call you Mexican, Guatemalan. But here, in the United States, we are f*cking Latinos. We are one! I'm sorry, I normally don't talk about this stuff but I'm just sick and tired."

Earlier this month, Anthony also took Trump to task over what many consider to be his xenophobia.

"What does it matter how much money you have when everything that comes out of your mouth isn't worth 2 cents," Anthony recently tweeted. "Latinos, it's time to show who we are!!!!"

Despite Anthony's best efforts in slowing Trump and uniting Latinos in opposition, a recent Quinnipiac University poll showed him leading the crowded Republican field with 28 percent of the vote, more than double that of closest challenger Ben Carson with just 12 percent.

Meanwhile, GOP candidate Jeb Bush, who is fluent in Spanish and whose marriage to Mexican-born Columba Bush strengthens his ties to the Latino community, has only 7 percent support, tying with Marco Rubio and Ted Cruz.
