The 51-year-old previously had a gastric bypass to lose a massive 11 stone, but the weight loss has left her with excess skin.
However, Tina denied that she was getting the surgery for her husband Paul, who is 19 years her junior.
Appearing on This Morning, Tina said: "Two weeks today I'll get my face lift and plastic surgery.
"I'll be under the knife… eyes, neck everything. It's not about doing it for him, it's about doing it for me.
"It's for me to feel better, it's the cherry on the cake. I've lost the weight, I'm eight stone side, I'm a size six but I have this horrendous skin."
Tina and Paul were on the show to discuss Stephen Fry getting engaged to partner Elliot Spencer, who is 30 years younger than him.
Former Shameless star Tina insisted she sees nothing wrong with the age gap. She said: "He's a highly intelligent man, he's no fool.
"He's probably been round the block like I had. I just don't see the problem."
