Jennifer Hudson Cancels CBS Concert Due to 'Abdominal Pains'

Jennifer Hudson hits the stage at Central Park’s Rumsey Playfield on Friday (June 10) in New York City.

The 29-year-old singer and actress performed as part of Good Morning America‘s Summer Concert Series.

Jennifer was also scheduled to sing on CBS’ Early Show the same day but had to cancel because of “severe abdominal pains,” her rep told JustJared.com.

FYI: Jennifer, who has dropped 80 pounds, just landed a book deal to write a memoir about her struggles with weight throughout her life. She “wants the book to serve as an inspiration for others who want to shed a few, and she’ll also offer tips on how to lose weight and keep it off,” CNN reports.
