Sunday evening's Tony Awards have been dedicated to those affected by the Orlando nightclub shooting that killed at least 50 people.

In a statement Sunday, the Tony Awards said "our hearts are heavy for the unimaginable tragedy." The awards, it said, will be dedicated to the friends and family of those affected by the most deadly mass shooting in U.S. history.

Organizers didn't say how the evening's broadcast would be affected. Lin-Manuel Miranda, the star and creator of "Hamilton" who's expected to be the night's big winner tweeted a rainbow-colored heart with "Orlando" written beneath it.

The Tonys are to be hosted by late-night host James Corden.
