The former One Direction member and his model girlfriend helped the girl get back on her feet, reported Ace Showbiz.
Gigi looked sporty rocking a red pantsuit and white sneakers while Zayn, 23, opted for black t-shirt and pants and finished off his look with a monochrome print jacket.
They were in New York City for the release party of his solo album "Mind of Mine".
The fan took to Twitter to explain what happened, "We were in a neat line outside the location and then Zayn and Gigi came out, causing everyone to start pushing against me and ended up making me trip over the security guard's leg, having me fall on the pavement.
