Kevin Jonas and wife Danielle Deleasa are reportedly getting ready to have their first child.

According In Touch Weekly magazine, the oldest Jonas Brother and wife Danielle were spotted buying a pregnancy test.

“An eyewitness spotted the happy couple at a Rite Aid pharmacy in West Hollywood on September 16 — and they were buying a home pregnancy test!” reported the site.

“They’re mature for their age, and they want to start a family,” a friend told In Touch Weekly. “They’d consider it a major blessing if Danielle was pregnant.”

Kevin, 22, and Danielle, 23, married last December at Oheka Castle on Long Island, NY.
