Diane von Furstenberg is once, twice, four times the grandma!
The designer’s son Alex and fiance, model Ali Kay, welcomed a bouncing baby boy into the world on Monday.
The proud parents named their little bundle of joy, Leon, after Diane's father.
As for how granny Diane's doing, she told the New York Post "All good! Love is life."
