Organizers of the Times Square New Year's Eve celebration screwed the last crystals onto the ball before it ushers in the new year one last time.

In just a few days, the ball in Times Square will drop. On Friday, rapper Pitbull helped install some of the final crystal triangles on the iconic ball.

The celebrations at Times Square in New York City will kick off in less than a week, with star-studded performances and an exciting countdown.

The last of the crystal triangles that make up this year’s Times Square New Year’s Eve ball have been installed, marking the first time in 10 years that all 2,688 were replaced at once. Rapper Pitbull and inventor Joy Mangano were on hand on Friday to help the co-organizers of the 2025 New Year’s Eve celebration in Times Square atop One Times Square to install the last few crystals.

Two new designs are etched into the crystals for this year's New Year's Eve Ball Drop. The 2025 One Times Square Crystal design features long linear cuts with a circle near the top. These symbols represent the iconic building and the 139’ pole that the ball slides down each New Year's Eve at midnight.
