Maude Apatow and Boyfriend Patrick Gibson Step Out at L.A. Event with Her Mom Leslie Mann (Exclusive)

It's a summer of love for Maude Apatow and Patrick Gibson.

On Sunday, Aug. 11, the Euphoria actor, 26, stepped out with her boyfriend Patrick Gibson, 29, who stars in the upcoming Dexter prequel Dexter: Original Sin at Jennifer Klein's annual "Day of Indulgence" event in Los Angeles.

The couple arrived with Apatow's mom Leslie Mann and were seen mingling with other attendees at the bash, including Kelsey Grammer, Dax Shepard and James Marsden.

In June, Gibson surprised fans when he shared a sweet snap of himself kissing Apatow — who commented "I love you" — on the cheek at a basketball game. "omg no way i didn't know y'all were dating!??? ahh you guys are cute!!" wrote a commenter.

Then in late July Apatow also made their romance Instagram-official. "before I got bronchitis," she captioned a carousel that included a photo of her and Gibson with her cat.

Others in attendance at Klein's annual event (where mini bottles of Don Julio 1942 and Don Julio watermelon margaritas were served) included Patrick Stewart, Tell Me Lies' Jackson White, Lukas Gage, Sam Claflin and more, who all left with Samsonite luggages.

Sarah Michelle Gellar, Patrick Dempsey and Christian Slater have all been confirmed to join Dexter: Original Sin, which will follow Dexter (Gibson) as he evolves into a serial killer.

Slater is set to star as Dexter's father, who teaches his son a code of behavior to help him "find and kill people who deserve to be eliminated from society without getting on law enforcement's radar," according to Paramount+.

Meanwhile, HBO announced Euphoria will be heading back into production for season 3 in January 2025 with the main cast, including Apatow, Sydney Sweeney, Zendaya, Jacob Elordi and more all set to return.
