After much speculation, it was finally confirmed that After School's Jooyeon, f(x)'s Victoria and Sori will become the three new members of G7 on Invincible Youth. This annoucement was confirmed by PD Kim Ho Sang on May 31st with the trio replacing the outgoing Hyuna of 4minute, Yuri and Sunny of SNSD who filmed their last episode on May 19th. PD Kim said, "Although most of us know Jooyeon for her looks, she will now show her straight talking personality through the show. As for Victoria, we know all about her flexibility but she will show more of her other charms in the show." Finally, "Sori is a bit of an unknown in variety and it was a surprise for us to cast a non-girl group member. Sori has an awesome dancing background and has majored in ballet since she was young. She has also released single albums and we look forward to seeing her variety qualities on the show." Their first recording will take place this week and will be shown in mid-June.
