Meghan Trainor, Charlie Puth Honor Orlando Shooting Victims at D.C. Pride Show

'We are going to sing extra loud tonight for Orlando.'

Meghan Trainor and Charlie Puth paid tribute to the victims of the Orlando nightclub shooting during their sets at a Washington D.C. Pride event on Sunday.

The singers, who performed at the Capital Pride Concert, offered their support to the LGBTQ community and expressed condolences to those who were affected by the tragedy. Forty-nine people, including two Massachusetts residents, were killed during the massacre, which is being labeled as the deadliest mass shooting in U.S. history.

Prior to her performance, Trainor encouraged the crowd to sing and dance as loud as they could in honor of Orlando.

“We are going to sing extra loud tonight for Orlando,” the Nantucket native said. “This set is for all those that we lost last night, so I want to see all your hands up for this set. I want to hear you singing and dancing. This one is for them.”

Puth, a Berklee College of Music alum, also addressed the Orlando tragedy before a performance of his hit song “See You Again.”

Here in Boston, a vigil will be held for the Orlando shooting victims at City Hall Plaza at 6 p.m. on Monday. Mayor Mary Walsh and Gov. Charlie Baker are expected to attend the ceremony.
