United Kingdom, Oct. 6 -- Jessica Simpson "feels better now" than she did in her 20s because she has "more confidence".

The 45-year-old pop star divorced her second husband Eric Johnson - the father of her three children - earlier this year and Jessica has admitted her life is good again because she feels happier and more confident.

She told PEOPLE: "I wear life with more confidence. I feel better now than I ever did in my twenties. I think going through life and having all the opinions thrown at you, I'm at the place where only my opinion matters.

"And of course my kids. I don't want to embarrass my children!"

It comes after Jessica previously admitted she feels "blessed" to have "gone through the hard stuff" in her life as she's now...
