Nadine Coyle is proving she is the best sister with a sweet birthday tribute to her sibling Rachel.
The Girls Aloud star shared a rare snap of Rachel in honour of her big day.
Captioning her post: “Happy birthday my beautiful sissy!!!! Love you with every atom of my being.”

Finishing off her message with: “Xxx love you!!! [Rachel] Have the most amazing time & year ahead.”
Plenty of the girls’ friends were quick to send Rachel their birthday wishes in the comment section.
DWTS judge Arthur Gourounlian, who actually used to perform with Girls Aloud back in the day, wrote: “Happy Happy Birthday Raaaaaaachel we love you”
Singer Samantha Mumba said: “Happy Birthday gorgeous!!”
