Heather Graham, 53, wows in a flirty floral dress alongside boyfriend John de Neufville as they lead stars at The Skatepark Project Gala in LA

The Skatepark Project used its 2023 gala to honor legendary skater Tony Hawk for his 20 years of tireless dedication promoting the organization's mission statement.

Actress Heather Graham and her boyfriend, snowboarder John de Neufville, were among the celebrities and high-profile people on hand to lend their support.

The evening included a cocktail hour, dinner, auction and performance, as well as a VIP afterparty to follow. 

The Austin Powers: The Spy Who Shagged Me star, 53, showed off her figure in a flirty floral minidress.

She also wore a pair of open-toe heels and had her blonde locks flowing long and straight several inches past her shoulders with a part in the middle.

John, 47, showed off his casual-cool style by pairing a black blazer with blue jeans, a matching button-down shirt and green camouflage sneakers. 

Heather and John, who were recently seen enjoying a romantic getaway together in Italy, have been linked as couple since 2022.

While Heather is known for a slew of films that date back to the 1980s that includes Six Degrees of Separation (1993), Swingers (1996), From Hell (2001) and The Hangover Part III (2013), John has also left his mark on the world.

He holds the world record for the most vertical feet ever snowboarded in a year, which he accomplished in 2014 by snowboarding on every continent.

Jack Black, 54, was among the other celebrities to support The Skatepark Project, which was founded over 20 years ago to help increase access to safe and inclusive public skateparks for youth in under-resourced communities. 

The actor, comedian, and musician was his usual funny self, striking hilarious poses for the cameras in a black suit with red and lime fire embroidery along both sleeves and the cuff of his pant legs.

The School Of Rock star rocked a bushy beard and mustache combo, while his hair was grown out to about shoulder length.

The honoree of the gala, Hawk, looked cool in an all-black ensemble consisting of jeans, button-down shirt underneath a blazer, and matching sneakers.

The retired professional skateboarder, 55, who is considered a pioneer of vertical skateboarding, now directs much of his attention to various philanthropic activities, which includes being the founder of the Tony Hawk Foundation that's since been renamed The Skatepark Project.

At one point Jacka** star Steve-O (born Stephen Gilchrist Glover) joined Hawk for a round of photos together.

And of course, the two star couldn't resist showing off their flares for comedy. 

The Wildboyz star, 49, dressed to impress for the gala in black pants, a retro black and gray blazer, along with a matching dress shirt and tie, and black sneakers.

The Skatepark Project's mission is 'to help underserved communities create safe and inclusive public skateparks for youth,' according to its website.

Over the past two decades, the organization has helped support the creation of nearly 700 public skateparks in all 50 states by awarding more than $13 million. 

More than eight million visitors annually enjoy skateparks that The Skatepark Project has helped fund. 

Thousands of skatepark advocates worldwide have received guidance and advocacy training from the The Skatepark Project.
