Happy Birthday, Kelly!

Kelly Clarkson rang in her 43rd birthday with a festive celebration on The Kelly Clarkson Show—and she got a surprise she won’t soon forget!

Her birthday treat was delivered by none other than Ben Affleck and his “brother” and The Accountant 2 co-star, Jon Bernthal, who were guests on the April 24 episode. Affleck rolled out three birthday cakes for the host, while Bernthal arrived with a stunning oversized bouquet of spring flowers.

“I didn’t know that was coming,” Clarkson said with a smile as she welcomed the duo to the couch. Affleck playfully responded, “You know how long we spent baking that? And Jon picked out the flowers.”

“Every single one,” Bernthal chimed in, before sharing that the dahlia symbolizes “inner strength.”

Clarkson, clearly impressed, responded, “I love flowers because of the language they speak.” See more inside and video clip…
