MANILA -- Dubbed as their most mature project ever, "Barcelona: A Love Untold" has taken KathNiel to a whole new level.

It was not surprising that Daniel Padilla's parents-- Rommel Padilla and Karla Estrada-- were in full support during the movie's red carpet premiere on Tuesday.

Padilla and Estrada even drew attention as they sat side by side inside the cinema.
