Christina Aguilera shared some rare snapshots of her daughter Summer Rain to commemorate her 7th birthday. The singer, 40, paid tribute to the little “vibrant spirit” on Instagram on Tuesday, Aug. 17 with a series of adorable photos edited on some sweet collage backgrounds with strawberries. Her little girl wears cute sunglasses and makes silly faces in the snapshots, and even has a mouthful of French fries in one.
