Matteo Guidicelli serenaded the studio audience of “ASAP” on Sunday as he celebrated his 24th birthday on the musical variety show. The “Galema” actor performed John Legend’s “All of Me,” which he said is his favorite song. When asked by host Robi Domingo if he's dedicating the song to anyone, Guidicelli just smiled and didn't answer the question. Sarah Geronimo, who is Guidicelli's rumored girlfriend, also sang the same song weeks ago.
