Watch Ariana Grande's Manchester Benefit Concert Live

Today, from 2pm to 5pm EST, Ariana Grande is livestreaming her One Love Manchester benefit concert. Proceeds from the event are going to the victims of the terrorist attack that took place at the pop star's concert two weeks ago.

“After the events last night in London, and those in Manchester just two weeks ago, we feel a sense of responsibility to honor those lost, injured, and affected. We plan to honor them with courage, bravery, and defiance in the face of fear. Today’s One Love Manchester benefit concert will not only continue, but will do so with greater purpose,” Grande's manager Scooter Braun tweeted Sunday morning. “We must not be afraid, and in tribute to all those affected here and around the world, we will bring our voices together and sing loudly."

Just a few days earlier, Grande surprised victims of the attack in their hospital rooms. "I met my queen," one fan tweeted.

This event is coming just one day after another terrorist attack on the London Bridge that killed seven people and injured at least 48.

There is going to be top security at the concert today as well, to ensure everyone's safety. “Ariana’s new security team consists of ex-military and is said to be the best in the business,” a source close to Grande exclusively told Radar. “She is going to have 24-hour surveillance and from now on, no matter what the cost is.”
