Mariah Carey shows off baby bump
Mariah Carey showed off her baby bump at US President Barack Obama's Christmas In Washington concert.
The singer, who is expecting a baby with her husband Nick Cannon, wore a red lace dress which clung to her healthy baby belly as she sang for the crowds.
Annie Lennox and Maxwell also sang at the concert, which raised money for the Children's National Medical Centre.
The festivities, hosted by comedian Ellen DeGeneres, took place at the National Building Museum in Washington.
The entertainers sang Christmas songs and performed for the Obama family - including first lady Michelle, daughters Malia, 12, and Sasha, 9, and First Grandmother Marian Robinson.
Also performing at the benefit concert were Miranda Cosgrove, who stars in the Nickelodeon TV series iCarly, and Matthew Morrison, who portrays the optimistic high-school music teacher in the TV show Glee.
The concert will air in American on Friday.
