The `Firework` singer - who tied the knot with the British funnyman in India last month - claims the love and support of her spouse made her feel more comfortable posing topless for a recent magazine spread.
She said: "I`m confident in my skin lately. I take care of myself and I also think that when you`re in a supportive relationship you don`t care any moreabout outside. Things that maybe would have irked you before don`t matter because you found someone who loves you no matter what.
"So I guess it`s a mixture of `Hey, I`m 26 and I know these are my prime years and I feel confident,` and being loved-up."
While Russell makes Katy feel confident, she admits not all of her previous relationships have left her feeling good about herself.
She added to Britain`s Cosmopolitan magazine: "You should be able to be in a relationship with someone who loves you for you, not someone who wants you to change. And it can happen to anyone, no matter how strong you are.
"That`s the power of love and sometimes love can be negative."
