Rosalka star Isabelle Abiera celebrated her 18th birthday in style. Aside from her grand debut party last August 29 at the Hotel Intercon in Makati, her showbiz friends like Nikki Bacolod and Megan Young also threw a surprise spa party for her held at the Organic Rituals Spa last September 18.  Since she is already of age, ABS-CBN.com asked her if she already has a boyfriend. 'Alam ko super showbiz answer, pero wala kasing naniniwala sa akin kapag sinasabi ko yun, pero wala talaga kasi ever since nung nagsimula ako sa Wowowee and then Rosalka wala na akong oras.”

But there are speculations that she and Rosalka co-star Felix Roco have a 'special relationship,' something reinforced by the fact that the latter was her escort for her debut party. 'Actually, kasi magkakilala na kami before. Kasi friends kami even before nag-start yung Rosalka kaya pinili ko siya as escort ko not only because katrabaho ko siya. Ayoko ng traditional na debut pero since pinilit ako ng mga tita at tito ko, naging traditional yung debut ko. As my escort hindi niya ako iniwan from the beginning [of the program] to the end.'

As a person who easily panics over little troubles, she said that Felix was a big help to her on her big day as he was always trying to calm her. 'Sobrang supportive siya sa akin nung araw na iyon kasi yun ang birthday present niya sa akin, gusto niyang maging happy ako that day because alam niya na mabilis ako ma-stress kasi may pagka-OC (obsessive compulsive) ako so alam niya na sobrang stressed ako nung araw na iyon. He came to pick me up and said, 'It's okay, don't worry, basta be happy lang.' We help each other. Takot siya sa tao, he does not want big groups, hindi siya very outgoing in that sense, very shy siya pero nag-enjoy naman siya.'

When ABS-CBN.com asked him if there is a possibility that the relationship will bloom into romance, she said, 'Like ko siya as a person, magaan siya kasama, mabait siya, I think I admire him. I don't know, we'll cross the river kapag may bridge na.' Rumor has it that they are closer to each other than Felix is to Rosalka's lead star Empress. 'Siguro mas comfortable siya sa akin kasi magkakilala kami outside of showbiz kasi si Empress at siya magka-batch sila sa Star Magic but the thing is, they met in showbiz. We have common friends. That's why naging close kami kasi he is close to my friend.

'Parang may chemistry lang, yes, may nararamdaman ako, may chemistry naman kami. Feeling ko sa kanya yung personality niya hindi siya open, pero that's the way na nagkakasundo kami kasi we 're just quiet pero nagkakaintindihan kami. Hindi siya madaldal or anything, chill lang siya, yun ang relationship namin, close kami na we know each other and we understand each other.'
