When it comes to the issues that effect us all, celebrities often join together to make a statement and take a stand. And that's exactly what Jennifer Aniston, Sofia Vergara and a number of Hollywood stars are doing as they filmed a public service announcement to call for an end to gun violence in the United States.

According to The Huffington Post on Wednesday, the A-list stars worked with gun control advocacy group Everytown for Gun Safety to plead for legislative action following the mass shooting at a holiday work party that left 14 dead in San Bernardino, CA last week.

Along with President Barack Obama, Spike Lee, Julianne Moore, Amy Schumer and a number of high-profile celebrities, the ad was released to encourage people to call lawmakers to address gun violence, which has increasingly become a hot national topic over the course of the last few years. Last week's San Bernardino shooting was the deadliest since the 2012 massacre of a Kindergarten class at Sandy Hook Elementary School in Newtown, CT.

"Thoughts and prayers alone from lawmakers aren't enough: we demand stronger gun laws to protect our children, families and communities," Shannon Watts, the founder of Moms Demand Action for Gun Sense in America, a part of Everytown for Gun Safety, said in a statement.

She added, "This weekend, we're honoring the victims and survivors of gun violence, and we're showing our continued commitment to changing America's culture of gun violence. In 2016, we will use our voices and votes to make gun safety a make-or-break issue for political candidates."
