WATCH: Jennifer Lopez Tells Fans Of Ben Affleck To 'Back Up, B**ch'

Ben Affleck is Jennifer Lopez's man, and she's not shy about letting his admirers know it.

A video shared by TMZ and X17 showed the singer-actress, 54, jokingly telling a group of women in a car to stay away from her 51-year-old husband.

Lopez enjoyed a relaxing weekend outing with Affleck in Los Angeles that culminated in a dinner at The Ivy on Sunday night.

In the footage, the couple was seen leaving the restaurant together and heading to their car, with Affleck opening the door for her before going to the other side of the vehicle.

As the "Gone Girl" star was about to open his door and take the driver's seat, a group of fans driving by briefly stopped next to Affleck to tell him, "We love you!"

In response, Lopez jokingly clapped back at the women, "Back up, b--ch!"

Her statement immediately sparked laughter from onlookers and even Lopez herself, while Affleck sat in the driver's seat calmly, apparently unfazed by his wife's antics.

Before having dinner at The Ivy, Lopez and Affleck were photographed shopping at the flea market in Hollywood earlier that day.

The "Hustlers" actress donned a beige turtleneck sweater, light wash flared denim pants and white platform heels for the outing. She accessorized her outfit with lightly tinted sunglasses and a chic brown handbag.

The "Air" actor-director, on the other hand, kept it casual in a gray T-shirt with a lightning bolt motif, blue jeans and colorful Nike sneakers.

Photos published by the Daily Mail showed the couple holding hands as they walked around their local market.

 Affleck appeared to have purchased what looked to be a painting of a flower at one point during the outing.

This came a day after the couple attended the 2023 LACMA Art+Film Gala, presented by Gucci at Los Angeles County Museum of Art.

Lopez rocked a semi-sheer gold gown and nude platform heels as she posed on the red carpet with her husband, who looked dapper in a black tuxedo.

The couple was first engaged in 2000 but called off the wedding. They eventually reconnected in 2021 and tied the knot on July 16, 2022.
