The 35-year-old singer revealed via Instagram on Thursday that she's about to be a mom of three, as she is expecting her second child with husband Ross. The two are already parents to 4-year-old daughter Jagger, while Simpson shares 11-year-old son Bronx with ex-husband Pete Wentz.
Simpson announced the news with a photo of her and Ross holding up her positive Clear Blue pregnancy test.
"We are pregnant and we are so excited to share it with everyone. Baby #3 ♥," she captioned it.
