It's been a while since SBS wrapped up their popular variety program, 'Heroes', but it looks like former castmates�Seo In Young and T-ara's Jiyeon managed to remain close friends. Seo In Young recently tweeted, "Long-awaited reunion," before posting photos of herself with Jiyeon. The two stars were backstage at a music program, and were dressed in their stage outfits. Fans immediately pointed out that they looked like sisters similar in age, thanks to their short haircuts and Seo In Young's ever-youthful looks. It's almost hard to believe that there's a difference of 9 years in age! Fans commented, "You're both goddesses," "It would be fun to have an unni like Seo In Young," and "I don't feel the age difference at all!" Source + Photo: TV Report via Nate
