Jessica Simpson is ready for 40!
Simpson, 39, will be ringing in her next decade on Friday and commemorated the milestone by trying on some vintage jeans from her twenties.
"I have kept these throwback True Religion jeans in my closet for 14 yrs (Iâ€™m not exaggerating!)," Simpson wrote on Instagram, sharing a mirror selfie of herself rocking the denim, which she paired with a black and purple sweatshirt.
"I figured that since Iâ€™m in the final hours of my 30â€™s Iâ€™d give them another try, and hello 40, so nice to meet you," the mother of three added.
The author celebrated another major milestone this week -- her wedding anniversary with husband Â Eric Johnson.
"Eric Johnson, my Husband, I love you. 6yrs ago today I married my perfect soulmate," she wrote. "Our unity was written in Godâ€™s sky of colliding stars. Together we manifest dreams, nurture desire, and hold space. Destined, it always has been and always will be, forevermore."
She added that a crystal butterfly from Johnson was her "dream gift."
She concluded the post with a quote from Emily BrontÃ«'s Wuthering Heights: "Whatever our souls are made of, his and mine are the same."
Earlier this year, Simpson released her memoir,Â Open Book, in which she opened up about her relationship with John Mayer, her marriage to Nick Lachey, her struggles with drinking, and plenty more bombshells.
