And on Thursday the 39-year-old blonde fashion designer shared an image with her 5.2M Instagram followers of her third child enjoying her big day.

Birdie also had what looked like a floral crown on her head. There was a gold balloon in the shape of the number one and balloons that looked like flowers.

Jessica and her 40-year-old husband Eric Johnson as well as their other two kids – son Ace Knute, age six, and daughter Maxwell Drew, age seven – have been self-isolating at their Los Angeles area home for the past week.  

Jessica seemed emotional in her caption for the cute image.  

‘Happy 1st Birthday my angel Birdie Mae!’ began the Dukes Of Hazzard actress. ‘You have created in me a healing purposeful life to live most fully and love most deeply.

The little girl was in her gold star pajamas with her blonde hair combed as she sat on a staircase. 

Earlier this month, the fashion designer gave a rare look inside her mansion in Hidden Hills, California.

She purchased Ozzy and Sharon Osbourne’s old home in 2013 for $11.5M. 

The cover girl was in all black as she stood in the foyer complete with a table that had several framed pictures on it and blossoms.

There was also a spiral staircase and a crystal chandelier. 

Simpson has been celebrating the success of her memoir, Open Book, which is on top the New York Times best seller chart, all year.

‘I wrote this book thinking if it could help one person get through their struggle it would be worth it. To find out that I have sold enough copies to make me the #1 New York Times best seller is humbling and surreal,’ she said.

‘I pray every day that I can use my platform for good. I promise to continue to be open and to lead with my mistakes. I promise to be honest and use the voice that God gave me.

‘Thank you guys for standing by me and supporting me. This is a dream come true. #OpenBook.’

In the memoir, Jessica speaks candidly about various aspects of her personal life, including her high-profile marriage to Nick Lachey between 2002 and 2006.

And the blonde beauty recently admitted she regrets not getting a pre-nuptial agreement when they tied the knot, as she was convinced they would be together forever.

Jessica said: ‘I wish I would have signed a pre-nup. That’s the funny thing: Nick wanted me to sign a pre-nup and I was so offended.

‘I’m like, ‘But we’re going to be together for the rest of our lives. We’re saying our vows to God and in front of all of our family and friends. This is never gonna end.′ And we didn’t sign a pre-nup.’

Simpson’s GiftGate has still been in the media.

Hoda Kotb told Nick and Vanessa Lachey that it was sweet of them to send Simpson a gift.

Vanessa famously became enraged during the Today show interview as she clarified they never sent a gift to the pinup and in fact don’t even have the blonde beauty’s address. Later Jessica said she never did receive a gift from the pair.
