Donald Trump keeps hinting about various celebrities who may show who up in Cleveland when the Republican National Convention starts next Monday.

Now Caitlyn Jenner's gone and scooped him.

Jenner says she'll be in Cleveland on July 20th -- although don't look for her at Quicken Loans Arena, where presumptive presidential nominee Trump and his as yet unnamed running mate will be the main attractions. Instead, transgender icon Jenner will be one of the featured guests at a brunch at the Rock and Roll Hall of Fame hosted by The American Unity Fund, a conservative nonprofit organization that does advocacy for LGBT Americans.

Jenner, a Republican who at one point supported Texas Sen. Ted Cruz's presidential bid, has said she wants to be an advocate for LGBT issues in politics — even comparing it to another world she knows plenty about, big time sports.

"The party conventions are like the political Olympics, and I'm excited to be headed to Cleveland to stand with my fellow LGBT Republicans and allies," Jenner, the 1976 Olympic decathlon gold medalist when she was known as Bruce Jenner, said in a statement sent to The Daily Beast. "As a proud Republican and transgender woman, I want to support courageous Republicans who advocate for LGBT freedom ... I want to do my part to persuade more Republicans to support freedom for millions of LGBT Americans."

Jenner will be introduced at the brunch by TV personality Montel Williams, a conservative activist and advocate for the LGBT community. She told the Daily Beast she has no plans to attend the convention, which runs from July 18 - 21.

She has had kind words for Trump in the past, though. Back in April, she posted a video thanking him for voicing opposition to North Carolina's recently passed and signed "bathroom bill," specifying that people use the bathroom that corresponds to their gender at birth.

“Last week Donald Trump said I could take a pee anywhere in a Trump facility," Jenner said in the video shot at Trump Tower in New York, that followed her as far as a restroom door. "So I am going to go take a pee in the ladies’ room."
