Kevin Jonas and his wife Danielle have welcomed their first child together, a baby girl. The boy band star revealed yesterday that his other half had gone into labour. A few hours later and the first picture of the new arrival was posted on Twitter. Dreft, a laundry detergent company with whom the proud parents appear to have a deal with, tweeted the above snap along with the caption: “On this day, a little star was born. Meet Alena Rose Jonas.” Kevin retweeted the news before adding: “I’m so in love with her.” And it wasn’t long before his brothers voiced their congratulations. Nick wrote: “My grandfathers memorial was yesterday. Today we welcome a new addition to the jonas family. God is great. Can’t wait to meet my new niece [sic].” Joe echoed this sentiment with the tweet: “As one life ends, another begins. Incredibly happy to be an uncle for the first time. Welcome to this world my beautiful niece [sic].” Danielle and Kevin have just welcomed their first child. [Top image courtesy of Twitter/ @Dreft]
