Lady in lace: Vanessa Hudgens turns heads at charity fashion event in trendy fit-and-flare dress and patterned tights

She turned 24 on Friday and enjoyed a romantic evening in New York City with boyfriend Austin Butler.

But on Monday Vanessa Hudgens was stepping out solo - and turning heads - in a black lace number at a charity event.

The former High School Musical star updated her fit-and-flare dress with a matching blazer, booties, and tights which had a sexy vine pattern scaling her legs.

Model Jessica White was also in attendance. 

The 28-year-old beauty wore a glittering sequinned gown with a sexy middle slit and pungling neckline, which she styled with black Christian Louboutin booties, a studded belt and layered necklaces.

Playfully posing for photographers, she kicked a leg up and held up a full champagne glass as she joined other guests in an elevator.

Rose McGowan echoed Vanessa's style in all black.

The actress sported a blonde bob and pink lipstick, and put a hand on her hip to accentuate her curves in the fitted, cut-out number.

Meanwhile, Vanessa's outing on Monday came days after she celebrated her 24th year with her actor boyfriend, Austin.

The couple were pictured bundled up on the roof of New York's iconic Empire State Building, with the beautiful skyline and the spectacular city lights to enjoy.

The Sucker Punch star and her beau have been glued to each other's side since they started dating 14 months ago, with lavish public displays of affection left and right.

The pair managed to keep their lovey-dovey behavior on the back burner while taking in the Los Angeles Lakers vs New York Knicks game at Madison Square Garden on Thursday.

Instead, Vanessa was seen clinging to Austin's arm with her head on his shoulder as she watched the players in action.

The actress' budding career seems to be right on track as well.
