Right now I’m pretty single... My career is my boyfriend.

Aguilera’s quip frames professional ambition as a substitute for (or priority over) romantic attachment. By calling her career her “boyfriend,” she uses a playful metaphor to normalize being single and to signal emotional investment in work—time, attention, and loyalty—typically associated with a partner. The line also pushes back against celebrity culture’s fixation on women’s relationship status, implying that fulfillment and identity can be anchored in creative purpose and self-direction. Read more broadly, it captures a modern, media-savvy stance: intimacy with one’s craft can be as sustaining as conventional coupledom, at least for a season of life.
