The 58-year-old entertainer left professional dancer Pernice open mouthed after she grabbed his face, kissed his lips and pushed him to the floor.
Speaking about the kiss, Pernice said: “Look she’s left me with red lips.”
Explaining her impromptu improvisation, McGee told host Claudia Winkleman: “That wasn’t in the routine. In the rehearsal I wasn’t kissing him so he didn’t expect it.”
Viewers were blown away by McGee’s bold move with one tweeting: “Was Debbie meant to kiss Giovanni on the lips? What a minx!”
Others voiced their jealousy at the kiss: “No words for Debbie, that was phenomenal. I'd happily kiss Giovanni again #strictly.”
