The singer recognized her 42nd revolution around the sun by snapping a few photos of herself strutting a bold metallic outfit in Vietnam. Aguilera, who celebrated her birthday on Dec. 18, shared the series of stunning images on Monday via Instagram, commemorating the look with the quirky caption, “✨BIRTHDAY energy ✨.” She rocked a plunging bronze patterned bodysuit with silky maroon joggers, a sleek black blazer, strappy heels, and sporty gold shades. Her mauve lip and bleach blonde beach waves completed her bombshell look. Given the international location and the clean, symmetrically-decorated long and narrow background, the Burlesque star must have hosted this celebratory pop-up shoot in her hotel, using the hallway as her makeshift runway. Her little birthday photo shoot became wildly popular with fellow celebs and loyal fans, who celebrated the pop star by showing love in the comments of the social media post. Real Housewives of New Jersey star Melissa Gorga gushed, “Happy birthday blonde bombshell 🍾🎉🤩.” Celebrity makeup artist Anthony H. Nguyen also wished the star well, exclaiming, “Happy birthday @xtina !! ❤️ you & hope you’re having a blast in Vietnam!! 🥂🍾🥳🎉.” Aguilera later posted two more carousels of images from her overseas celebrations on Instagram. The first follow-up she captioned, “BIRTHDAY wishes 🎂✨,” as it featured glowing pics of the singer posing with her sparkly decorations and private helicopter at a picturesque waterside event space. Although beautiful, she didn’t even need the decorations with the panoramic view of Vietnam’s unbelievable landscapes. She shared a more detailed view of her helicopter ride with her fiancé Matthew Rutler in a third post, which the singer accurately described as a “BIRTHDAY adventure ☀️✨.” Happy belated birthday, Miss Aguilera!
