Jessica Simpson "feels better now" than she did in her 20s because she has "more confidence"

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 able to focus on making music independently.

She told PEOPLE: "I was just in Pittsburgh to perform for the first time since 2008 for 60-plus minutes. It felt like home. It was such an adrenaline rush. It was beautiful for me.

"I'm actually blessed to have gone through the hard stuff that I went through. I feel like I'm on the other side. I'm proud to be doing music independently and have my kids rooting for me. It's more free than I've ever been."

Jessica also revealed in July that she was ready to start dating again. The singer was asked by Today show co-host Jenna Bush-Hager: "Are you interested in dating? Can I set you up with anybody?"

Jessica replied: "I'd totally jump on that. Yes I'm single - very into like, very ... I'm ready ... My type of person is one of a kind. I don't have a look, or anything.

"I just like for somebody to be individually, who they are. And exude confidence without the ego.

"It's hard to find but I feel like it's out there. I don't need somebody to be supportive of me all the time. "I feel like the independence that I have right now, if I can have that and give it to someone else, that'd be cool."

Jessica announced her split from Eric in January. The pop star wrote on Instagram at the time: "Eric and I have been living separately navigating a painful situation in our marriage.

"Our children come first, and we are focusing on what is best for them. We are grateful for all of the love and support that has been coming our way, and appreciate privacy right now as we work through this as a family."
