Brooklyn Decker soared hundreds of feet above the road for an exhilarating zipline run, and only ET was there to catch all the action.
"Alright, ET. Let's go!" the Grace & Frankie actress exclaimed before taking to the sky. "I hope I don't die."
The 29-year-old Sierra Club ambassador indulged her need for speed in the San Gabriel Mountains to promote the National Park Service's 100th anniversary.
"I grew up camping and spending time outdoors," Decker told ET. "I think it's just good for the soul, and it's fun."
Now that Decker and husband Andy Roddick are parents to 6-month-old son Hank, she's gotten started on raising the next generation of nature lovers.
"The trick is if a baby is crying, you take them outdoors, and it's kind of amazing how when they get outside, all of a sudden, they're just in complete wonder," Decker said.
While she still seems to be having the time of her life, Decker admitted that being a parent has called for her to dial it back when it comes to risky adventures.
"I have always been a little bit of a daredevil," Decker shared. "That's changing now that I'm a new mom. I'm definitely thinking about my child and his future, but, yeah, I always like to push the boundaries a little bit."
