Jennifer Lopez and Ben Affleck Twin in All-White at Malibu Cook-Off After Shooting Scare

Jennifer Lopez and Ben Affleck gleamed in matching outfits as the loved-up couple walked hand-in-hand towards the Malibu Chili Cook-Off on Sunday.

The Hustlers star, 53, wore a flowing sheer white gown, and she walked in bright red sandals with her hair tied up in a messy bun.

The Good Will Hunting actor, 50, wore a T-shirt covered in wavy lines, and he rolled his sleeves up to the middle of his forearms – while JLo carried a brown bag as they attended the festival, known for its good food, games and rides.

He added a pair of khakis and comfortable-looking white sneakers to his relaxed ensemble, along with reflective aviator sunglasses.

Looking fresh, his brown hair was cut short, neatly against his head as he enjoyed Malibu’s festivities.

But just hours before Ben and JLo’s sweet stroll, crowds were forced to storm out of the Malibu Chili Cook-Off after a child threatened that he had a gun.

Chaotic scenes ensued at the Labor Day weekend festival on Saturday night when the young attendee said he had a firearm – sending festival-goers into a frenzy as they climbed over barricades to escape.

Horrific clips showed the panic as families and young people fled to find their loved ones because of the suspected shooting.

But the Sheriff’s Office confirmed there was no shooting and Lost Hills deputies who investigated the scene found there was no threat.

It was ‘just a kid being stupid,’ Deputy Sean Cohen told DailyMail.com.

The happy couple were today joined by Jennifer Lopez’s kids, 14-year-old twins Emme and Max.

Bennifer’s appearance out came after the pair enjoyed a lavish wedding and honeymoon last month.

The sizzling showbiz hot couple held a fancy wedding at a plantation-style estate in Georgia last month and then traveled to Italy.

Jennifer gave her fans the inside scoop on her and Ben’s $8.9 million Georgia estate in her latest On The JLo newsletter Thursday.

While sharing the romantic details from their big day, which came just weeks after first tying the knot in Las Vegas, the superstar, 53, included a sweet photo of her rocking a white Ralph Lauren gown and handsome groom, 50, slow dancing under a neon sign, which read: ‘Mr. & Mrs. Affleck.’

‘When he saw me appear at the top of the stairs that moment it both made absolute sense while seeming still impossibly hard to believe, like the best dream, where all you want is never to awaken,’ she wrote recalled.

She continued: ‘I would have had many of the same thoughts probably had I not been focusing so hard on not tripping over my dress, but when I got close enough to see his face, it made the same wonderful sense to me.’

‘Some old wounds were healed that day and the weight of the past finally lifted off our shoulders. Full-circle — and not at all the way we planned it. Better,’ the Let’s Get Loud hitmaker gushed.

Ahead of the ceremony, Lopez revealed that ‘it had rained at sunset every day that week’ and everyone was getting worried about the heat, likelihood of thunder and lighting’ and if they would recuperate in time from the stomach bug ‘all’ of their family caught that week.

Despite others concerns with the ‘unexpected setbacks,’ Lopez insisted she ‘never had one doubt.’

‘All week I felt the calm and easy certainty that we were in God’s hands,’ she raved. ‘At six forty-five, Saturday, August twentieth, the sun broke free and cast its rays like little diamonds dancing across the river behind the makeshift altar in our backyard.’
