Kevin, Danielle Jonas prep for #babyjonas2 in funny announcement

There is something in the celebrity water supply.

You can add Kevin Jonas and his wife, Danielle, to the long list of stars who are expecting. Both parents announced on Twitter that they'll be adding to their Jonas bunch. Take a look at the fun photo below.

The oldest JoBro's eyes were playfully large while reading a pregnancy book, and his wifey looked happy to be giving into cravings that included cereal, Girl Scout Cookies, and Doritos. She might not have actually been eating all of the things, but for us, eating for two still qualifies as #LivingTheDream.

The new baby will make Kevin and Danielle's firstborn, Alena Rose, a big sister. And judging by this pic she's either really happy about her new responsibilities or that adorable glitter tee.

Nick Jonas shared a picture of the 2-year-old on Instagram and congratulated his brother and sister-in-law. "Can't wait to meet my next niece or nephew," the Close singer said. 

We're looking forward to the arrival of #babyjonas2 as well. Congrats to the expecting parents.
