Christina Aguilera's baby daughter is very "chill". The 'Beautiful' hitmaker and fiancé Matthew Rutler welcomed Summer Rain into the world five months ago and the blonde beauty feels "very blessed" to have such an easy-going infant. She said: "I have a chill baby, she's just so calm and so easy to make laugh and smile, she's just a breeze, thank God! "She's just so beautiful, these big blue eyes, she's just so gorge...very happy and feel very blessed having Summer Rain in my life." The 'Voice' mentor recently shared a picture of Summer Rain, taken from behind, and she admits she loves the picture because of the tot's "chunky legs". She said: "Her little tushy! The little chunky legs. I love it, I love to nibble on them."
