2009 was the year of addictive tracks that you couldn't get out of your head, such as 'Ring Ding Dong,' 'Sorry Sorry,' 'Gee,' 'Again and Again,' and 'Abracadabra.'
Has much changed in the last eight years? Infinite's Sungjong has uploaded a snap of himself from 2009 and compared it to one of him in 2017.
We see no difference. But it does beg the question, have other K-pop idols changed much between 2009 and today? We'll let you be the judge. Let's take a look...
1. SHINee's Taemin
With his solo comeback imminently upon us, has SHINee's maknae changed much over eight years? Here's a snap of Taemin from SHINee's '2009, Year Of Us' days compared to his recent comeback teaser. Looks like he's still got that look-to-the-floor down pat.
2. f(x) Amber
Amber's got more tattoos and piercings today than she did in 2009, when she debuted with f(x), but otherwise she pretty much looks the same.
3. 2PM's Taecyeon
Taecyeon enlisted in the army this year. Comparing a photo he recently uploaded of him in the army, with a 2009 photo from 2PM's 'Again and Again' era, it looks like he's even aged backwards!
4. Girls' Generation's Yoona
Yoona's youthful looks are definitely the envy of many. She still looks as young today as she did during Girls'Generation's 'Gee' promotions.
5. BIGBANG's G-Dragon
The BIGBANG leader made his solo debut in 2009 with 'Heartbreaker' and in 2017 completed his "Act III: M.O.T.T.E" solo world tour. He may have gone through many wildly different concepts in the last eight years but his smile remains as adorable as ever.
