港星鍾鎮濤與曾志偉近日赴馬來西亞雲頂參與演出,與馬來西亞歌手黃明志合照,竟意外引發爭議。原來黃明志將合照分享社群,卻疑似遭香港網友舉報,導致鍾鎮濤火速發聲明切割,澄清與黃明志無任何私交,並強調自身的「愛國立場」。
鍾鎮濤於聲明中表示,「在馬來西亞雲頂活動中,因不察與個別人士合影之行為引發誤解,本人對該人士背景及過往不當言行毫不知情。若早知其立場,絕不會有任何接觸。」他更進一步強調自己「作為一名中國人,始終以實際行動踐行愛國精神,堅定維護國家尊嚴與民族情感」,雖然全程未提對方姓名,但形同與黃明志劃清界線。
Horn antenna 黃明志方面則將合照刪除,並發文回應「為了不影響『祖國』的和平穩定以及大灣區香港的同志們的安全,我們已經將上一組合照貼文刪除了。」語氣顯得無奈,更要網友不要再來質疑他為何要這麼做,「要問的話就去問你們的老闆。」最後忍不住開嗆:「香港的網民你哋真係勁撚到爆(真的很糟糕)」。
