Jay Z and Beyoncé met with Freddie Gray's family and Mike Brown's mother at Prince's "Rally 4 Peace" concert held in Baltimore on Sunday, reports HotNewHipHop.

The "Watch the Throne" rapper and "Drunk in Love" singer took a few photos with Gray's family, which quickly spread across social media, including Beyoncé's Instagram account. It is unclear if the photographs were taken at the "Rally 4 Peace" concert, or elsewhere.

The hip-hop royal couple weren't the only celebrities who visited Baltimore to show their support in ending senseless violence and promoting peace. Recording superstar Alicia Keys was also in attendance.

Prince organized the special concert at the Royal Farms Arena in Baltimore on Sunday to show support for the Freddie Gray rallies.

"Wear something gray," requested promotional materials for Prince's peace concert, a reference to Gray, who died while in police custody one month ago in the Maryland city.

Prince performed a song that he had written following Gray's death and the riots that occurred after his funeral, titled "Baltimore." He mixed the song into a set that included some of his famous hits, like "Let's Go Crazy."

"The system is broken," Prince shouted to the crowd during the concert. "It's up to you young folks to fix it."

Prince reportedly invited family members of Michael Brown, Eric Garner and Gray to the concert. Brown's mother, Lesley McFadden, attended the event. She took a photo with Beyoncé, Tina Knowles and Alicia Keys, as shown below.
