Ariana Grande has paid tribute to her half-brother Frankie Grande on his birthday.

The 'Dangerous Woman' hitmaker - who shares the same mother, Joan Grande, with Frankie - has taken to social media to gush about her brother in a heartfelt post, which saw her wish her older sibling ''a bundle of sparkles and bright, beautiful energy'' on his 34th birthday on Tuesday (24.01.17).

Alongside an image of the pair as children, which sees the 23-year-old singer kiss her sibling, she wrote: ''happy birthday to a bundle of sparkles and bright, beautiful energy @frankiejgrande

I love you (sic).''

The brunette beauty continued to post a string of images of her and Frankie in their childhood on the photo-sharing site.

Another post simply tagged the former 'Celebrity Big Brother' contestant - who competed in the reality show last year - whilst the final post of the duo in fancy dress costumes was credited as her ''favourite'' image.

She wrote: ''favorite @frankiejgrande.

love you (sic).''

And Frankie - whose full name is Frank James Michael Grande Marchione - reposted the images on his Instagram account.

And the light-haired hunk has admitted his recent celebration was the ''greatest birthday'' of his ''entire life''.

Alongside a picture of him on Instagram beside his birthday cake, he wrote: ''Quite possibly one of the greatest birthdays of my entire life. Thank you to everyone who made it happen. My fam, my friends & especially you #grandtourage! I love u all from the bottom of my heart! #birthday (sic).''
