The 37-year-old tied the knot with 31-year-old Parrish in a ceremony in upscale Montecito, California, on Saturday surrounded by his children, friends and family.
Hart later shared a photo of him with his new bride, along with his son Hendrix,(8), and daughter Heaven, (11), in their wedding finery on Instagram, and sweetly captioned the shot, "'#Harts what's understood doesn't need to be said!!!! #LiveLoveLove."
The couple, who have been together for over seven years, showed off their wedding-day looks — he wore Davidson Petit-Frére, she wore Vera Wang.
In a chic Instagam post, Parrish is wearing her beautiful white gown with a sheer lingerie-style bodice with spaghetti straps and a mermaid train while Hart and his son are suited and booted in black tuxedos.
Parrish wore a different Vera Wang design for her party look. A sheer, fitted ivory gown that was finished with long sleeves and an open back.
The Ride Along starshared videos of the build-up to the big day on Snapchat, with the first clip showing him walking along a beach in California with his bride-to-be.
In another video, he is cuddling his young son Hendrix. "Hanging out with my best man. My best friend a.k.a., my best man," he added. He told Howard Stern in an interview earlier this year that Hendrix would have a big role in his wedding. "My son is my best friend. My son will definitely be my best man," he told the shock jock.
Celebrity guests at the nuptials included rapper-turned-actor Ludacris, along with his wife.
The marriage means Parrish will be stepmother to the comedian's two children, who he shares with ex-wife Torrei Hart. The former couple split in 2011 after eight years of marriage.
Hart and Parrish got engaged almost two years ago, when the Ride Along star popped the question to his longtime love on her 30th birthday. Despite being together for five years before they got engaged, the actor confessed in a recent interview that he already feels married.
"I already feel married, the wedding is really just for her," he told Entertainment Weekly.
He also told the magazine despite his box office success, he always puts his family first. "Regardless of my level of success, I don't ever want to lose the family feeling of a home," he confessed.
"I don't want to be in a mansion where I have to find my kids on the east wing. I want to sit on the couch and be able to yell into the kitchen, 'Hey come on, let's go outside and ride a bike!' I like two dogs, I like a fence. I don't need no dolphins. I don't need a shark in my shark tank."
