After writing a long, heartfelt letter to fans expressing her gratitude, the singer, 32, debuted a music video for her single "Let There Be Love."
Svelte in a monokini several times throughout the video, a glowing Aguilera appears with friends, fans and family, including her boyfriend Matthew Rutler and son Max. Close friends Nicole Richie and Christina Milian make cameos as well.
"Hey everybody, Christina here, just thanking you guys so much for filling my life and my heart with so much love," she says at the beginning. "I appreciate all your support. This one's just for you."
