WATCH: Anne Curtis singing 'Alone': Ang pangit ng boses ko!

MANILA – Anne Curtis did it again. In a mall show for one of her endorsements on Sunday, Curtis fearlessly took the stage to treat the live audience with her signature rendition of Heart’s 'Alone.' For her attempt to show off her vocal chops, Curtis drew loud applause from the audience every time she hit the high notes. But in video captured by ABS-CBN News, the highlight of her performance was when she started to sing ahead of the tune. The actress giggled when she realized her mistake. At the end of her performance, Curtis said, “Ano ba ‘yan, ang pangit ng boses ko today!” The last time Curtis performed 'Alone' in public was during one of the commercial breaks of the Binibining Pilipinas beauty pageant grand coronation night last March 30. The 'It’s Showtime' host is set to hold her new concert series dubbed 'The Forbidden Concert: Round 2: Annekapal' starting May 16 at the Smart Araneta Coliseum.
