In her latest Instagram post, the "Oops...I did It Again!" singer put on a fashion show for her followers to show off all of her clothes before she switches over to a maternity wardrobe.
"So I have to model my clothes now before I really start showing 🤰🏼," she captioned the video, which features the blonde beauty rocking multiple looks and showing off her midriff.
"I actually do have a small belly here but at least my pants 👖 fit 😬😬😬😬😬😬 … Well barely 😅🤷🏼♀️," Spears quipped.
The Princess of Pop — who already has two sons with ex-husband Kevin Federline: Sean, 16, and Jayden, 15 — announced her pregnancy on Monday, April 11, telling her 40.6 million Instagram followers that she received a positive pregnancy test result.
Asghari, 28, later confirmed the pregnancy news, writing: "Fatherhood is something i have always looked forward to and i don’t take lightly. It is the most important job i will ever do," in his own Instagram post.
In her initial announcement, Spears explained she "won't be going out as much due to the paps getting their money 💴 shot of me," like they have in the past.
The "Toxic" singer's first two pregnancies were highly publicized at the height of her fame, with Spears and Federline calling it quits on their marriage shortly after the birth of their second son.
Spears also opened up about her struggle with "perinatal depression" during her previous pregnancies, which is speculated to have been the reason behind her infamous 2007 unraveling that ultimately got her placed under a conservatorship the following year.
"It’s hard because when I was pregnant I had perinatal depression," she revealed in Monday's post. "I have to say it is absolutely horrible 😔."
"Women didn’t talk about it back then," Spears continued. "Some people considered it dangerous if a woman complained like that with a baby inside her … but now women talk about it everyday …hank Jesus we don’t have to keep that pain a reserved proper secret 🤫 😬😬😬."
"This time I will be doing yoga 🧘♀️ every day !!! Spreading lots of joy and love 💕," the performer concluded the announcement.
Celebs have since wished the songstress congratulations on her bun in the oven, including her longtime pal Paris Hilton and ex Federline, who reportedly "wishes her the best for a happy, healthy pregnancy."
