The decision came after the fifth ballot cast by the 115 cardinals since the papal conclave began Tuesday.
Some celebs took to their Twitter accounts to show their support. Nicole “Snooki” Polizzi wrote, “Yay for Pope Bergoglio!! He's adorable.”
Piers Morgan tweeted, “Pope Francis 1 is known as a frugal, humble, moderniser. Sounds just what the Catholic Church needs.”
George Lopez cracked, “Please call me Pope JORGE!," while David Arquette wrote, "Don't call the new pope Francis - his name is Frank - If you call him Francis he's gonna kill you."
Kathy Griffin also quipped, "If I were you, I would NOT call Oprah today. She's walking around her mansion...'oh great I went to Argentina for nothing.'"
Bergoglio succeeds Pope Benedict XVI, who became the first pope to resign in hundreds of years. He stepped down February 28, citing advanced age.
Cardinal Jorge Bergoglio of Argentina has been elected Pope to lead the world’s 1.2 billion Catholics. He is the first non-European pope of the modern era. He has chosen the name Pope Francis I.
