It's only the first day of September, but fans at G-Dragon's concert in Manila must have been thinking it's Christmas already when Sandara Park made an appearance roughly halfway through the show.

The two performed "Hello" for the first time in years, drawing shrieks from concertgoers lucky enough to be at Araneta Coliseum Friday night.

The abundance of fans who brought out their smartphones the moment Park emerged from behind the stage meant there's no shortage of photos and clips of the rare performance.

Park's appearance was announced a week before G-Dragon's scheduled concert, much to the delight of fans who have been "shipping" the two as a couple.

Early this year, rumors surfaced claiming that Park and G-Dragon were dating after fan videos showed them cuddling after Big Bang's concert January 8. G-Dragon is a member of Big Bang.

YG Entertainment, Park and G-Dragon's talent agency, was quick to douse the rumors and said the moment fans caught was staged as a joke.

Park added: "We were playing a joke. People from the company teased me saying that G-Dragon had me in a headlock. I don’t date at work."

G-Dragon's performance was part of his "Act III, M.O.T.T.E 'Moment of Truth The End' " world tour.
