Huh... russian is late... as usual... u've figured out already. Yeah, her name is Irina Toneva and she's the member of the band Fabrika. Blondie is there too. As well as the 3rd girl who's not on the first pic but is on the next 2. Other guys on the first pic are also from star Factory. Toneva also has very popular duo with Pavel Artemyev (the guy near the blondie). Their song "Понимаешь" (ponimayesh) was really loved by audience. So although these 2 are in different bands now, they often sing this song at concerts.
