The Jonas clan is about to get even bigger. On Monday (April 25), eldest JoBro Kevin Jonas shared a hilarious baby announcement with wife Danielle.

"Prepping for baby number two! #babyjonas2," he captioned on Instagram, as he reads What to Expect When You're Expecting Again, while Danielle is surrounded by food.

The couple's first child, two-year-old Alena Rose, will be a big sister in the coming months, and she clearly couldn't be happier about it. Uncle Nick Jonas shared this pic of his niece after hearing the good news. (Danielle also shared it on Twitter.)

"I love his girl so much... So happy for my brother and sister in law. Can't wait to meet my next niece or nephew! @kevinjonas @daniellejonas #alenarose #babyjonas2," the "Chains" singer wrote.

Congrats to the Jonas family!
