Jessica Simpson is spilling her relationship secrets!

In a guest post for Glamour, the newlywed shares her five vows for finding her "happily-ever-after" with hubby Eric Johnson.

"Now that I’ve planned a wedding, gotten married, gone on my honeymoon, and come back to life again, I've had some time to reflect on how life’s challenges and accomplishments have brought me to where I am right now," she writes. "I am married to the love of my life and am constantly trying to be the best mom I can be for Maxwell and Ace."

"Today, I feel truly comfortable in my own skin," the blonde beauty continues. "Better exercise habits, food choices, and lifestyle changes have contributed to this, but ultimately, my confidence comes from my state of mind."

She adds that having a supportive partner is important and to "let him love all of you. Eric has seen me at every size, and he loves me no matter what."

"When I was younger and starting out in the music business, I always felt like I was being defined by other people ... It took a while, but now that I’m in my 30s, I’ve grown into myself and established my identity on my terms," she adds.

"I didn’t want to deprive myself or give up the foods (and cocktails!) I love in order to feel beautiful on my wedding day," she admits. "And, because of what I learned from Weight Watchers, I didn't have to. I gave myself plenty of time to get my body where I wanted it to be, and I learned to make balanced choices during the process. The moment I put on my gown, I was proud that I had let myself celebrate along the way."

We're happy to see that Jess is in such a great place -- see the rest of her tips over at Glamour.
