December Avenue share the stage with Regine Velasquez – watch

December Avenue and Regine Velasquez-Alcasid just shared the ASAP stage and blew everyone's minds.

On Sunday (06/09), December Avenue returned to the noontime variety show to perform the opening number of ASAP Natin 'To for the first time with Asia's Songbird. Together, they played crowd favorites 'Kung 'Di Rin Lang Ikaw' and 'Sa Dulo ng Walang Hanggan.'

In a tweet, vocalist Zel Bautista revealed that while writing what would be December Avenue's massive hit 'Kung 'Di Rin Lang Ikaw,' he was thinking of Ogie Alcasid's ballad 'Bakit Ngayon Ka Lang.'

Bautista also thanks Velasquez-Alcasid on Twitter, writing, "It's an honor po!"

Velasquez-Alcasid is currently a judge on ABS-CBN's Idol Philippines with Moira Dela Torre, James Reid, and Vice Ganda.

December Avenue are slated to embark on their first US tour this September to October, following their debut Canada tour that kicks off in July.
