Ariana Grande celebrates brother Frankie on 42nd birthday

Ariana Grande is honouring her brother Frankie on his 42nd birthday.

The Oscar nominee, 31, gathered words of appreciation for her elder sibling in an Instagram post as he turned 42 on Friday.

"Happy birthday to this beautiful human being @frankiejgrande !!!!!!!!!!!!!!!!!!!!!!" Ariana began in the caption of a picture of her and her big brother sharing a hug.

She continued, "I am so proud of you! thank you for being such an inextinguishable bright light and inspiration in all of our lives, for your heart that is larger than life, and bringing so much joy everywhere you go!!!"

"You are sunshine personified and we are all so lucky to know and be loved by you," the Wicked star concluded before signing off with, "I love you."

Frankie reposted Ariana's endearing Story by thanking her for being his unconditional support system.

"Weeping. I love you so much my sister. Thank you for ALWAYS being there for me. Can't wait for all the adventures we will go on together on this rotation around the sun. I'm so blessed to have you in my life."

Frankie has also been as supportive towards his younger sister as he previously shared his pride over her role in the hit film Wicked.

"I saw it 12 times in the theaters," Grande said in a statement, per CBS News. "I am just so unbelievably proud of her, you know, like, I always say, like, it's like if you had a sibling that was a neuroscientist and they won, like, the Nobel Prize, that's how I feel about my sister."

On the professional front, both actors and singers are leaving their mark in the musical fantasy genre as Ariana just earned an Oscar nomination for best supporting actress with her role as Glinda in Wicked, while Frankie is bringing his Broadway flair to Nickelodeon's superhero franchise Henry Danger: The Movie, now streaming on Paramount+.

"I'm just so blessed that I get to play a villain that just wants everyone to sing and dance," the publication quoted another of his statements.

Frankie is also working on his own music, recording as Frankie Grande, not Frankini.
