'Real Housewives of Beverly Hills' star Kim Richards admits she dated Donald Trump

Donald Trump has quite a colorful dating history -- but no one expected this!

In a clip of the upcoming "Real Housewives of Beverly Hills" reunion, Kim Richards dropped a bombshell about dating the now-president. Watch the jaw-dropping clip here.

"I heard a rumor that you once dated Donald Trump," host Andy Cohen asked Richards. "Is that true?"

"Yes," the reality star confirmed.

It seems like none of the other "RHOBH" cast members knew about this, including Kim's sister Kyle, because they all looked taken aback by the question.

However, the reality star dodged any further questions about the matter.

"Let's not get into it," she said. "I had dinner with him. I had dinner with Donald."

Of course, co-star Lisa Vanderpump just had to ask: "Sex or not?"

To which Kim replied with a few laughs: "Let's just leave it at this. I don't want to talk about the president."

Way to leave everyone in suspense! Of course, if Kim and Donald managed to make things work long-term, her days would've be spent in the White House shaking hands with international leaders.

"Kim could have been our first lady!" Cohen said.

The former "Celebrity Apprentice" host has dated a number of other famous women who also could've ended up as first lady. Trump was briefly linked to actress Kara Young in 2001, but their relationship came to end amid a scandalous love triangle involving TV host A.J. Benza. The billionaire businessman had a thing for models, including Playboy stunner Victoria Zdrok.

He is now married to Melania Trump, who has made headlines ever since Donald announced his presidential run. Check out her style transformation in the slideshow below:
