7. Christina Aguilera & Matthew Rutler

Despite her high profile, pop star Christina Aguilera has maintained a long-time relationship with guitarist Matthew Rutler. They first met back in 2010 during the production of the singer’s movie Burlesque. Rutler served as a production assistant. They started dated shortly thereafter and moved in together in Mulholland Estates in 2013. Their relationship went up another level in 2014, when they announced they got engaged. Since then, they remained so for around seven years.

Together, they have a daughter, Summer. From her previous relationship with Jordan Bratman, Aguilera has a son. While they have been quite happy with one another and have made investments in their children, it seems that they’re not rushing on tying the knot. According to Aguilera, she wants to ‘cherish’ the moment and not feel ‘rushed’. She added that she wants to spend more time with her family and work for now.
