Singer Cyndi Lauper says she's disappointed with Donald Trump's anti-gay marriage stance.

The real estate mogul, host of NBC's Celebrity Apprentice, and possible 2012 GOP presidential nominee has recently told numerous media outlets that he's opposed to giving gay and lesbian couples the right to marry. During a recent interview with the Christian Broadcasting Network (CBN), the billionaire entrepreneur said he's against marriage equality, then added that he opposes discrimination against gay people.

“Gay marriage,” David Brody said during the interview. “I know you're for traditional marriage, against gay marriage, what about civil unions?”

“To be honest with you, as far as civil unions are concerned, I haven't totally formed my opinion,” Trump responded, then added, “but there can be no discrimination against gays. I'm against gay marriage. I took a lot of heat for that.” (The video is embedded in the right panel of this page.)

Lauper, who appeared on Trump's reality show last season to raise money to benefit her gay rights charity, True Colors Fund, told's Greg Hernandez that Trump's remarks were hurtful.

“We make strides and then they take it away,” she said. “I went on Trump, he embraced me and my charity and then he turned around and nullified everything. It broke my heart. I couldn't believe it. It hurt my feelings so much.”
