One of rock's royal families has just gotten a bit bigger.

Régine Chassagne and Win Butler, the power couple behind Arcade Fire, have welcomed a brand new seven-pound baby boy into the world.

Chassange gave birth to the boy on Sunday, April 21. News of which came, perhaps appropriately, via a holy man. Barry Mack, the pastor at Montreal's St. Andrew's Presbyterian Church Saint-Lambert, gave the good news to Le Journal de Montréal.

"C'était un mariage à leur image," said Mack of the couple. "C'est bien de voir qu'ils sont toujours ensemble et qu'ils ont aujourd'hui un bébé. C'est un peu rare dans l'industrie du divertissement."

Which, in english, is roughly, "It's good to see that they are still together and they now have a baby. It's a bit rare in the entertainment industry."

No mention of the new release has been made on the band's official sites, though well-informed Twitter fan account ArcadeFireTube is over the moon about it.

More Arcadelettes are forthcoming. Fellow Arcade Fire member Marika Anthony-Shaw is also pregnant.
