Me neither, I think she is Olvido though.
I only know Ylenia, Belen and the guy from Adan y Eva!
Yes, I think I heard Belén calling her Olvido.
I also know Ylenia and Belén, and Sandro Rey too. The videos of his show on youtube are so funny lol
EDIT: OMG, Olvido was in Campamento de Verano
, I didn't remember her. Jeyko at the studio defending her
