StarHub Cable Vision was fined 10,000 Singapore dollars (7,200 US dollars) for airing the commercial last November, the MDA said in a statement on its website.
The commercial on MTV's Mandarin channel promoted a song by singer Olivia Yen, the media regulator said.
MDA said it was a breach of television advertising guidelines, "which disallow advertisements that condone homosexuality."
Singapore defines gay sex as an act of "gross indecency," punishable by a maximum of two years in jail.
Prosecution, however, is rare.//dpa
