Selena Gomez and Lady Gaga join Billboard campaign to stop gun violence

(CNN)Selena Gomez, Yoko Ono and Lady Gaga are among a host of big-name artists who are taking on gun violence.

The stars are teaming up with Billboard magazine to campaign Congress to pass stricter gun regulations. Over 180 musicians and music executives signed an open letter in this week's edition of Billboard with the cover reading, "Stop Gun Violence Now."
Among the stars are: Jennifer Lopez, Katy Perry, Lin-Manuel Miranda, Zayn Malik, Paul McCartney, Sting, Barbra Streisand, Britney Spears, Ellen DeGeneres, James Corden and Tony Bennett.
The cover, which features the signatures of those who signed the letter, comes on the heels of the the deadliest mass shooting in U.S. history at an Orlando nightclub this month and the ongoing debate over legislative stalemate on the issue on Capitol Hill. Also mentioned in the letter is the murder of singer Christina Grimmie, who was killed the night before the Pulse shooting at a fan meet and greet.
    "The one thing that connects the recent tragedies in Orlando is that it is far too easy for dangerous people to get their hands on guns," the letter reads. "We call on Congress to do more to prevent the gun violence that kills more than 90 Americans every day and injures hundreds more."
    The petition comes after the Senate failed to approve four new gun control proposals on Monday. The Billboard petition calls for support of a proposal to make it "illegal for suspected terrorists to legally buy guns" and "require a background check for every gun sale."
