A Pink Na-Eun, Chorong, Bomi, Naeun, Namjoo, and Hayoung uploaded a happy-go-lucky greeting to fellow member Eunji in celebration of her birthday!

The footage was filmed backstage at the 'SHINZU'I White Concert' held a few days ago. Due to her busy schedule, Eunji was unable ot attend the event, which probably made it a bit easier for her members to film the surprise greetings.

Each girl takes turn sending a birthday message after they sing a cheery verse of Happy Birthday together. Eunji will have to decide for herself which of the members "loves her the most", though it's obvious she is well loved by them all.

The above photo was posted to A Pink's official Facebook with the caption, "A Pink's main vocalist Miss Eunji's birthday is today, August 18 2014. Everyone please congratulate the multi-talented Eunji for her birthday." Their official cafe also posted photos.

In addition, fans all over the world joined together on SNS with birthday tweets for Eunji, whose name was trending early this morning.
