How about holding your Sweet Sixteen at the sweet Sistine?

Pope Francis is allowing the endangered Sistine Chapel to be rented out for a corporate event, with the proceeds to benefit the needy — while at the same time cracking down on visitors to the world’s most famous church.

Porsche will be the first to hold an outside fundraiser amid Michelangelo’s fragile frescoes. The luxury German auto giant is offering an exclusive tour of Rome, including a concert inside the chapel, at a cost of more than $5,100 a pop.

At the same, the Vatican said Thursday that it would cap the annual number of visitors at 6 million to protect the Renaissance masterpieces from the tourist hordes.

Dust, sweat and human breath have damaged the 500-year-old paintings, including the famous creation scene of God’s outstretched arm giving life to Adam.

Antonio Paolucci, head of the Vatican Museums, said “radical intervention” was needed to preserve the paintings, prompting the Vatican to install new climate and lighting systems to cut down on heat, humidity and dust.
