Christina Aguilera's rarely-seen son, 16, towers over her in unseen family photos
Christina Aguilera is a proud mom of two children but her son, Max, rarely features on her social media. The 43-year-old made an exception on Wednesday when she posted some "unseen bits" from her recent family vacation, which included photos of the 16-year-old, his sister Summer Rain, 10, and her fiancé Matt Rutler, 39.
