Kevin Jonas and wife Danielle Jonas expecting second child

Kevin Jonas and his wife Danielle Jonas are expecting their second child.

The 28-year-old singer and his wife announced the news Monday on Instagram with a photo of themselves reading "What to Expect When You're Expecting" and eating snacks.

"Prepping for baby number two! #babyjonas 2," the former "Married to Jonas" stars captioned the picture.

Jonas and Danielle met in the Bahamas in 2007 and married at Oheka Castle in New York in 2009.

The pair are already parents to 2-year-old daughter Alena Rose, whom they welcomed in February 2014.

"We are excited to share the news that we are expecting a new addition to our family this winter. Alena is beyond thrilled to be a big sister and we can't wait to meet the newest member of our family," the couple said in a statement.

Danielle told People magazine in October she and Jonas were "always talking about" giving Alena a sibling.

The couple previously told E! News they were "overjoyed" to become parents.

"We could not be more excited to start building our family together," the pair said after Alena was born.

Jonas came to fame with his siblings as the pop group the Jonas Brothers and later competed on "The Celebrity Apprentice." He also starred with Danielle on the E! reality series "Married to Jonas" in 2012 and 2013.
