Tiffany celebrated Girls' Generation's 8th anniversary since their debut!

She made the below posts to Instagram, posting, "x8 #Happy8thgirls," and telling her fans, "To our fans SONE that carry us through it all. Thank you x #8yearswithsnsd." The eight members of Girls' Generation can be seen next to a wax figure of Marilyn Monroe, putting on a similar expression. Tiffany also shared a photo of the fans all holding up pink lights to represent SONE.

Girls' Generation debuted with "Into the New World" in 2007 and most recently returned with the track "Party". 

Congratulations on their 8th anniversary!
