New mum Christina Aguilera has revealed her baby daughter's name — Summer Rain Rutler.
The singer, 33, shared the moniker, which appears to be a tribute to the season in which she was born, on Twitter: "So proud to welcome our beautiful daughter Summer Rain Rutler into the world," she posted.

Christina and fiancé Matt Rutland's first child together was born on Saturday 17 August via caesarean.
At around eight in the morning, the Beautiful singer checked in to the Cedars-Sinai Medical Center in Los Angeles, where other celebrity mums including Kim Kardashian and Jessica Simpson have given birth.
Christina and Matt will no doubt be overjoyed by the arrival of their new addition, who is a little sister for Max, the pop star's six-year-old son from her previous marriage to Jordan Bratman.

Earlier this year, film producer Matt popped the question during a romantic proposal in Hawaii on Valentine's Day.
The bride-to-be announced the news by tweeting a picture of the couple holding hands, her diamond sparkler clearly visible. "He asked and I said yes," she captioned the image.
A month later, Christina revealed at a concert that she and Matt were expecting their first baby together.
