Hilary Duff is expecting her fourth child.

The “Lizzie McGuire” alum announced the happy news with a hilarious Christmas card showing her posing with husband Matthew Koma, their daughters Mae, Banks, and son Luca who she shares with ex Mike Comrie.

The card reads,  “So much for silent nights.”

The back, meanwhile, confirms that she is “adding one more to this crazy bunch!”

“Surprise Surprise!”
