Britney Spears revealed her pregnancy through an Instagram post

Britney Spears said she is "having a baby" with her fiancé, Sam Asghari, in an Instagram post-Monday.

Spears said she took a pregnancy test after she noticed her stomach was "growing" despite recent weight loss after a trip to Hawaii.

Monday evening, Asghari added an Instagram post of his own accompanied by a painting of a lion family with three members.

The 40-year-old Spears has said she longed for a baby with the 28-year-old Asghari, a personal trainer, but she has said the nearly 14-year-long conservatorship forced her to remain on birth control.

The two met on the set of her “Slumber Party” video in 2016.

Spears has two teenage sons, Sean and Jayden, with former husband Kevin Federline.
