The actress recently locked in a sweet deal with Lionsgate for the thriller "The Housemaid," scoring a hefty $7.5 million salary -- putting her right up there with top dogs like her "Euphoria" costar Zendaya, who raked in $10 million for her tennis flick, "Challengers."

Unlike Zendaya, Sydney didn’t kick things off as a child star, so her rapid ascent to the top of Hollywood's A-list over the past few years is seriously impressive.

The actress got totally mobbed as she hit up the Writers Guild Theater in Beverly Hills for a special screening of her new flick "Maria" on Monday. As you can see, fans, autograph hunters, and paps were practically climbing all over each other for a moment with Ang, leaving her barely an inch of breathing room.
