Kaley Cuoco and her boyfriend just took a secret “trip of a lifetime” to Australia: Photos

Kaley Cuoco has just finished her Australian "trip of a lifetime" with boyfriend Karl Cook.

The 31-year-old actress shared a series of photos she captured while spending time with her professional equestrian beau, 26, and his family in Sydney and the Northern Territory outback.

She thanked the Cook family (who run an accounting software empire and have an estimated networth of over $2 billion) "for another trip of a lifetime", jokingly writing on Instagram that "we didn’t have any fun at all on this trip".

The Big Bang Theory star conveniently uploaded a gallery of images to Instagram of the pair taking in some of Australia’s best sights:

The duo appeared to fly in about a week ago and, after a quick cruise around Sydney harbour, they headed to the Greater Western Sydney AFL Game on July 29^th – getting some cute pics along the way.

Kaley, Karl, and the Cook family then flew to Alice Springs, going for a hike around the monolith and heading to Bruce Munro’s art installation Field of Light.

They even managed to do the entire 10km hike around the rock, with Karl sharing this hilarious picture to Instagram.

After filing from divorce from tennis player Ryan Sweeting in 2015, Kaley began dating Karl in March 2016, and the pair have been inseparable ever since. They even adopted a miniature pony together earlier this year.

Speaking to Sharon Osbourne on The Talk last year, Kaley said she can’t stop smiling these days.

“We met at a horse show,” she told the talk show host. “I finally found my horse guy. It was very meant to be.”

She went on to gush that her partner exhibits the exact same personality traits as her.

“We share a passion for horses and dogs, and all of that,” she said. “It’s been so lovely.”
