While hosting Saturday Night Live, Gal performed a skit which had her impersonate top models Kendall Jenner and Gigi Hadid.
In the faux E! reality TV series Model House, "Kendall", "Gigi" and sister "Bella" sit around a table talking about who's prettier out of the three of them.
"I'm under so much pressure," Gal (as Kendall) says, before turning to Gigi and announcing: "You're prettier than me."
"No way, you're so much prettier than me," Gigi replies.
The advert for another reality TV show, Kendall's World, then plays which shows Kendall getting lost in her own house while trying to find the bathroom.
Watch the hilarious clip below.
