The Internet went buck wild after Kaley Cuoco shared an Instagram photo of her horse wallpaper on Wednesday, so ET tracked down her interior designer, Jeff Andrews, to get the skinny on the Big Bang Theory star's recent remodeling.

"Kaley's a very accomplished equestrian and loves horses and all animals," Andrews told ET. "I saw this Hermes paper that was horses, and she was like, 'Oh my God! I love it! Where are we putting it?'"

The kitchen proved to be the perfect place for the wallpaper, which retails for $345 per roll. The job is estimated to have cost close to $4,000 for the whole job, including labor.

"We ended up re-doing pretty much the entire house," Andrews revealed.

The pair also worked on Cuoco's guest room, adding some pops of fur with along with more subtle wallpaper, as well as in a nook of the house. The 30-year-old actress showed off a custom table in the latter area, which featured a leg shaped like a talon.

While Cuoco's home makeover wasn't cheap, Andrews shared a simple tip for those looking to remodel without spending a fortune.
