Kathy Griffin has been working with her "celebrity voice doctor" Sia to get her "voice back".
The comedienne recently revealed she has had half of her lung removed after being diagnosed with stage one cancer and has shared a video of her hanging out with her friend Sia as the singer helps her to "get her voice back".
Giving fans an update on Instagram, she wrote: "Working on getting my voice back with a special visit from my celebrity voice doctor. Enjoy!"
In the video, Kathy explained how she was struggling to talk.
She said: "Hi you guys. Here's an update. So my surgery has been I think, three weeks and my voice is still hoarse as you can tell, but my doctor has been giving me vocal exercises. And the weirdest thing happens which is when I sing my voice is fine, like watch ..."
She then started mouthing the words to Sia's track 'Chandelier', only for her to move the camera and show Sia singing in her place.
She added: "Did I mention my doctor is Sia? Very strict."
Kathy previously admitted she thinks her post-surgery voice will "scare people".
She said: "I’d like to start to post little videos about my recovery and stuff, but my voice is like, really hoarse and I don't want to scare people."
But the star was quick to find the funny side of things, as her own croaky voice left her giggling.
She added: "I'm laughing, it's just even that notion [is funny]. For some reason, I'm laughing at everything now. And if it's horrible, I laugh way more!"
Kathy revealed her diagnosis earlier this year, and it was a big shock for her because she's never smoked.
She said: "I've got to tell you guys something. I have cancer. I'm about to go into surgery to have half of my left lung removed.
"Yes, I have lung cancer even though I've never smoked! The doctors are very optimistic as it is stage one and contained to my left lung. Hopefully no chemo or radiation after this and I should have normal function with my breathing."
