Grammy-winning rapper Eminem is making a difference. Slim Shady has announced his involvement and support for a British Red Cross campaign in light of this week’s deadly Manchester bombing.

Em went to Twitter this week to reveal the action he’s taking and to request fans to get involved.

On Friday, pop singer Ariana Grande released an emotional message about the bombing happening after her Manchester show.

Earlier this week, Ariana reunited with boyfriend Mac Miller following her concert’s deadly aftermath.

The 23-year-old singer was greeted by her boyfriend, rapper Mac Miller, in Boca Raton, Florida, on Tuesday at the airport, after a suicide bomber killed 22 people at her concert in Manchester, England, on Monday night. Grande, wearing a black hoodie and holding a blanket, was clearly emotional reuniting with 25-year-old Miller, and appeared to be fighting back tears. (ET Online)
