The Hollyoaks actress and her pro partner Matt Evers impressed the judges last night with her skate to 'Skinny Love', which earned her 18.5 points.
Robin Cousins described Porter's skate as "exquisite" and a "breathtaking duet", while Louie Spence billed it as "beautiful".
Katarina Witt claimed that Porter brought "the first sparkle of magic to the night".
Porter is now the bookmakers' favourite at 13/8 to win the competition, while over 65% of Digital Spy readers claimed that Porter was the best performer of the night.
Her nearest rival was Olympic star Chemmy Alcott, who picked up 7.9% of the vote.
Dancing on Ice continues next Sunday (January 15) on ITV1.
