Pull Only One Field In Relations

Hi guys ,

i have this in my Product model relations

'title'=>array(self::HAS_ONE, 'ContentTypeMedia',  array('nid' => 'nid'),'on'=>'field_media_general_lang_value='.$language),

but when i need to print the title i use

echo $product->title["title_column"];

anyway to be able to use it like

echo $product->title

as from title model i will be using only one column !

Thank you
