Nick and Joe Jonas celebrated the birthday of one special little lady.

The brothers shared special messages to their oldest niece Alena Rose, daughter of Kevin and Danielle Jonas, on Instagram Friday. Though Nick, 25, was in Mexico City to open for Bruno Mars’ 24K Magic Tour, he was thinking of the birthday girl.

“Happy birthday to my beautiful niece Alena! You light up my world every single day. Love you so much!” wrote the Golden Globe-nominated singer, who is the godfather of Alena Rose’s sister Valentina Angelina.

Meanwhile, uncle Joe, 28, was in Sydney, Australia, where he has been filming a new season of The Voice Australia as a first-time coach.

The DNCE frontman, who is engaged to Game of Thrones‘ actress Sophie Turner, shared a screen grab from his FaceTime call with Alena Rose on his Instagram Story Friday.

The Jonas love comes after fans speculated that a Jonas Brothers reunion is imminent after their dedicated Instagram account was reactivated after almost five years of silence.

However, Nick dispelled the rumors on the E! red carpet special ahead of the 2018 Grammy Awards when Ryan Seacrest asked him to clarify if he was getting back together.

“We hung out for a weekend all together and I guess our Instagram was restarted,” Nick explained. “Right now there’s no reunion planned. But never say never — you never know what’s going to happen.”

The band split up in 2013, with Nick telling PEOPLE at the time that they were stepping back because “prioritizing our family is really important to us.”

Kevin added, “We’re choosing our family because it was becoming toxic.”
