Christina Aguilera and fiancé Matthew Rutler are glowing parents-to-be. The 33-year-old pop superstar shared a sweet snapshot of the beaming duo on her Instagram account on Thursday. The Grammy winner Aguilera looks casual chic, sporting a flowing gray T-shirt and a gray wool coat. The singing sensation’s platinum locks are slicked back in a bun and she finished the fresh maternity look with a pair of sunglasses and a pop of bright pink lipstick.
