Concha Velasco is Petra -- hard to understand the article with my limited Spanish, so we may need to wait for VV to return to clarify, but it looks like she's going to be the sister of Doña Aurorita (aka, the woman who owns the dress shop that Ana used to sell the dresses to). Apparently, Aurora has died and now Petra has the shop.
Even more interesting is that she is the also the former love of Emilio...and there's something in the article about Emilio wanting her to use the shop she gets from Aurora to help Ana's career, and if I'm understanding this correctly, Petra agrees but only if she can get to work with them.
Aitor Luna is Humberto Santamaria -- this guy will be playing a movie star with a huge ego who will be the new face of Raul's line for men. At the end of the article is an insinuation that the storyline will reveal the man he's been hiding under his mask.
So...possible love interest for Raul? Or for one of the other characters?
I hope Carlos is not going to marry Ana and baby daddy is coming soon coz the show is not good without the tension or suspens they both bring but I hope that atl is the can find out he has a child pleaseeeee
