What Stars Are Saying on Social Media About Tonight's Presidential Debate

Tonight's presidential debate between Hillary Clinton and Donald Trump is must-see TV and many celebrities will be watching from home, as well as the front row.

Billionaire entrepreneur and "Shark Tank" co-star Mark Cuban has already confirmed that he will be taking a front-row seat at the debate at Hofstra University on Long Island in New Yorkto cheer on Team Hillary.

"Obviously, I'm a not a Trump fan. I am a Clinton fan," Cuban told ABC News today at the red carpet premiere of "Shark Tank." "I think she'd make a great president.

"I don't think he's got the skill set," he said about Trump. "Let's put it this way, if he came on 'Shark Tank,' I wouldn't make the investment. I just don't see him as being capable in the least bit."

Trump quickly responded to the news by tweeting that he was considering inviting Gennifer Flowers, the variety show performer who famously had an affair with former President Bill Clinton.

Although Trump's campaign manager told ABC News' George Stephanopoulos that Trump did not actually invite Flowers, it seems she was willing to accept the invitation.

Meanwhile, other celebrities are gearing up to watch the first debate between the two candidates. Here's what they are saying on social media:
