The Toxic singer shared the news in an Instagram post, saying that she took a test after her partner, Sam Asghari, made fun of her for being “pregnant for food”. Spears had previously stated that it “wants a family” with the 28-year-old fitness model. The announcement comes several months after the 40-year-old Spears was released from a conservative deal that has dominated her daily life for more than a decade. During the court hearings that led to the ruling, Spears argued that she had to remain in control of the births despite her wishes. The couple got engaged in September last year, with Spears joking that the proposal was “too late”. Announcing the news on Instagram, Spears wrote: “I lost so much weight to go on my trip to Maui just to get it back… I thought ‘What happened to my stomach ???’” My husband said “No, you’s pregnant idiot!” “So I did a pregnancy test … and ohhhh, well … I’m having a baby … 4 days later I got a little more food pregnant. Grows up.” The pop superstar said that “she will not go out much” after her announcement. Spears already has two children, Sean and Jayden, whom she shares with her ex-husband Kevin Federline.
