The former pop star took the snap in her bedroom at the home she shares with husband Eric Johnson and their kids Maxwell, eight, Ace, seven, and Birdie, 15 months. 

In the caption alongside the picture, Jessica wrote: ‘I have kept these throwback True Religion jeans in my closet for 14 yrs (I’m not exaggerating!).

She added: ‘I figured that since I’m in the final hours of my 30’s I’d give them another try, and hello 40, so nice to meet you.’

On June 26, she had also looked towards her milestone birthday, posing on the beach in a bikini and hat and posting the image to Instagram with the words: ‘YEE-HAW to my final days in my 30’s.’

Just a few days ago, on July 5, Jessica and her husband celebrated their sixth wedding anniversary.

They tied the knot in California in 2014 after a four-year engagement.

‘Eric Johnson, my Husband, I love you. 6yrs ago today I married my perfect soulmate,’ the Texas-born star star wrote next to a picture of the couple on Instagram. 

‘Our unity was written in God’s sky of colliding stars. Together we manifest dreams, nurture desire, and hold space,’ she said. ‘Destined, it always has been and always will be, forevermore.’ 

The couple’s anniversary came just days after they celebrated their son Ace’s seventh birthday with a baseball-themed party. 

Eric, 40, a former NFL tight end, is Jessica’s second husband.

In 2002, she had married 98 Degrees boybander Nick Lachey; they divorced in 2006.
