There is a saying that only one out of every 10 people is good-looking.  Next time you’re in a crowded place, take a gander. You’ll see that it’s mostly true (unless you’re in a room full of swimsuit models – in that case, go you!). So, when narrowing down the top 10 hottest first ladies (and mistresses), I did a little math. There have been 44 presidential wives. If the saying holds true, that means only 4.5 are aesthetically pleasing. Ouch. No wonder there are so many mistresses. The ironic thing about the mistresses, though? John Kennedy had the most, but he had the hottest wife. Go figure.

10.  Helen Herron Taft

OK, so maybe ol’ Willie’s wife Helen Herron didn’t smile a lot, but she had nice eyes. That counts for something. She was by far better looking than him. She knew how to sport some cool jewelry, too. Slap a smile on that face (and maybe some Frizz-Ease) and she’d probably move up a few notches on the list.

9. Grace Coolidge

Calvin’s wife Grace looks more like a soccer mom than a hot wife, but there’s just something about Grace that draws you in. And, the fact that she was one of the founding members of Pi Beta Phi sorority at the University of Vermont only proves that, on the inside, Grace was a hot party girl.

8. Louisa Adams

John Adams was 30 when he married 22-year-old Louisa. Louisa was a looker, especially for the early 1800s.  And it looks like she had a rockin’ bod, too. John made the right choice when he picked Louisa over her plain-Jane sister Abigail.

7. Gennifer Flowers

Bill Clinton’s taste in women doesn’t touch former playboy president John Kennedy’s, but at the end of the day this list just wouldn’t be complete if it didn’t include one of Bill’s scandalous affairs, because – frankly – Hot.Hillary.Is.Not. So we had to go with Gennifer Flowers on this one. You remember Gennifer. She gladly told the world about her affair with Bill and he blatantly denied it on “60 Minutes.” In the end he ‘fessed up. Poor Bill. Seems to be a pattern.

6. Jane Wyman

Jane was pretty hot in her acting days, but long before she played bitter Angela Channing on “Falcon Crest.” Besides the fact that she won an Oscar for Best Actress in “Johnny Belinda,” she still holds the title of being the only ex-wife to a U.S. president. In the words of Paris Hilton, “that’s hot.” I bet Ronnie and Jane whooped it up Hollywood-style before they split and he got hitched to ol’ Nancy.

5. Judith Exner

It’s interesting that Judith Exner resembles Jackie Kennedy because she was allegedly one of John’s (many) flings. We will give it to John, though, he did pick the hot ones (as you’ll see). Apparently the dudes were drawn to Judith, as she reportedly had affairs with a handful of famous cats – Frank Sinatra included.

4. Blaze Starr

Let’s face it. Johnny boy was having affairs left and right, but at least he went for the sexy burlesque dancer (OK, stripper) and not the White House intern. Apparently Blaze had it for the politicians (or vice versa) because she allegedly had a long affair with Earl Long, too, governor of Louisiana.

3. Jayne Mansfield

Jayne Mansfield was H-O-T! One of the first American sex symbols, Jayne was yet another of John Kennedy’s alleged mistresses. Apparently he (along with dozens of other men) liked the Playboy Playmates. It was said that Jayne got around and even flaunted her nipples in front of other actresses’ men. Talk about a hot little number.

2. Jackie Kennedy

We have to give serious props to Jackie Kennedy, right? She is the classic beauty. Gay men and lesbians all over America would even consider Jackie a hottie. John may have dipped his nuggets in a variety of sauces, but he always came home to Jackie.  Jackie is No. 2 on this list because, sigh, she is not the hottest. Classiest, by far. Hottest? We can’t honestly say so, which leads us to …

1. Marilyn Monroe

Enough said.
