New uncles Joe Jonas and Nick Jonas meet their niece Alena for the first time

New uncles Nick Jonas and Joe Jonas have met their baby niece Alena for the first time. Nick and Joe, who along with their brother Kevin shot to fame as The Jonas Brothers, posted several touching pictures of the special moment on Instagram.

"Welcome to this world Alena Jonas," wrote Joe alongside a sweet image of himself cradling the tot. "#littlebaby #shessosmall #woah."

"My beautiful niece Alena Rose," Nick simply captioned his photo of the new arrival.


Nick's girlfriend Olivia Culpo also paid new parents Danielle and Kevin Jonas a visit.

21-year-old, who was crowned Miss USA in 2012, uploaded a photo of herself holding sleeping Alena.

"I got to meet this beautiful angel today," she wrote. "Alena Rose Jonas. Congrats @daniellejonas @kevinjonas."

Eldest brother Kevin is the first of the musical Jonas siblings to become a father. The 26-year-old and his wife Danielle welcomed baby Alena on 2 February.

He announced on Sunday that "baby Jonas" was on the way, and a photo of the newborn was released via the account of laundry detergent Dreft, the same day.

"On this day, a little star was born," wrote proud father Kevin along with a photo of his glamorous wife gazing at her tiny daughter.

The timing of Alena's arrival is particularly significant for Kevin, Joe and Nick, whose grandfather recently died.

"My grandfather's memorial was yesterday," tweeted Nick on the day Alena was born. "Today we welcome a new addition to the jonas family. God is great. Can't wait to meet my new niece."
