But while they're in Rio for the Olympic Games, they've decided to just hang out together — off a cliff!
Their latest escapade started with a confession from Jenna: "I actually don't like to do these adventure things with you. Just so you know."
Of course Natalie knew better, and she pushed her pal onward toward a remote destination that would allow them to be real daredevils.
Still, Jenna had her doubts, adding, "Every time I do something with you, it's some sort of torture."
But does this look like torture?
Well, looks can be deceiving — especially at Rio's famed Pedra do Telégrafo.
The cliff, which has a very convenient area of smooth rock just feet below, is a tourist favorite for snapping frightening-looking photos without any real risk.
The fun for these two, however, was completely authentic.
