The mom-to-be tells the new issue of Glamour magazine that she is going to “enter into mommyhood” at the start of next year. She’s a bit anxious about the upcoming arrival, her first. “I want to get it right,” she shares. Aguilera said she wanted to be a working mother, so she could “balance” the needs of her child with her career. Christina’s husband, Jordan, is “thrilled” about their upcoming arrival, she says. “He’s just great. He’s so supportive and amazing through everything. He came with me on the last leg of the tour and he was my support system… I gush. I’m a lucky girl.” Congrats!
