Playboy Playmate Sara Jean Underwood Shows Off Almost EVERYTHING in Hot, Steamy, Illegal? See New Pic

So, about Yellowstone: A tourist recently got a hefty fine for wandering off the walkway to collect some hot springs water and a buffalo calf had to be euthanized after some dumbass visitors thought it was cool and put it into their car. Oh, and a week or so ago, a guy wandered off, fell into a hotspring, and died. Roasting to death in nature's majesty sounds like one of the worst ways to go, right?

Well, not everybody's been following the rules or using common sense, apparently, because it looks like one very scantily clad model ... well, see for yourself:

That's actress, TV host, and model Sara Jean Underwood ... um, looking fine but also like she's going to get fined.

And, yes, she looks hot, and we're not just talking about the steam -- she was a former Playmate Of The Month.

It turns out that we're not the only ones concerned -- this picture got a series of replies on Twitter ... including one that was such an endearing gem that we absolutely had to share it with you.

@SaraUnderwood You are amazing but please stay on the pathways. Someone died a couple weeks ago because they didn't and fines are steep.

We're glad that so many people were looking out for her breast best interests.
