"For those haters out there who are gonna hate hate hate no matter what, let me inform you that I have not been able to breathe through my nose like a normal human being in years," the 29-year-old actress wrote. "This surgery is changing my life. With that being said, if I DID get a nose job, (which I didn't) I would be shouting that from the rooftops as well ��."
She also explained that the procedure is something she's been putting off for some time. "I have been putting sinus surgery off for year, and I finally did [it]," she Instagrammed along with some recovery pics and her dogs.
Kaley has indeed been open about plastic surgery in the past, specifically about getting breast implants when she turned 18.
"[It's the] best decision I ever made," she told Cosmopolitan magazine in April.
"I love them," she added to ET at the Los Angeles premiere of "Authors Anonymous" later that month. "I'm super happy. I would do it again in a heartbeat."
As for her current sinus surgery, Kaley's recovering nicely thanks to her supportive husband Ryan Sweeting.
"Coming out of sinus surgery and the first thing I see is my beautiful angel of a man, he's right there. Always," she gushed Friday on Instagram. "He's taking amazing care of me. ☺️I love my noodle. He's perfection. ��"
