Pop diva and "The Voice" coach Christina Aguilera is in Milwaukee today, gearing up for a private concert for Northwestern Mutual at the BMO Harris Bradley Center.

The company – celebrating its 160th anniversary – is currently in the midst of its annual meeting, bringing in to town the company's financial representatives from across the country for meetings, presentations and networking opportunities, all capped off by a big concert from a big name performer.

The celebrity performers for past years have included the likes of Maroon 5, Imagine Dragons, Kenny Chesney and Tim McGraw.

This year, that performer is Aguilera.

The annual meeting comes to a close tomorrow.
