But wait, there was more.

“Also it’s silk !!! I don’t even feel like I’m wearing anything and it’s a pretty color too !!!” the Oops! …. I Did It Again songstress added.

Spears filmed herself rolling around in bed wearing just the hot pink bra and light pink undies.

She said despite turning a year older, she still feels young at heart.

“40 can suck my d— !!!” she continued. “I turned 6 this year 🤦🏼‍♀️🤦🏼‍♀️🤦🏼‍♀️🤷🏼‍♀️🤷🏼‍♀️ I feel six most of the time anyways !!!”

Spears turned 42 on Saturday and spent her birthday alongside her mom, Lynne, and brother, Bryan.

Social-media posts shared by those in her inner circle showed Spears and her mom enjoying their time together.

She has also reportedly been bonding with her brother during her ongoing divorce from estranged husband Sam Asghari.
