Jennifer Lopez has strong 'mom look'

Jennifer Lopez only needs to use her "mom look" to reprimand her children.

The superstar has four-year-old twins Max and Emme with estranged husband Marc Anthony. Jennifer is currently on tour with Enrique Iglesias and her children have joined her on the road. Before her show in Los Angeles last Friday night, the twins were apparently being boisterous backstage – but Jennifer managed to handle the situation without having to say anything.

"[Max and Emme were] speeding around the green room area and causing a ruckus, almost running over people and running into things," a source told New York Post. "[Jennifer] was forced to come out of her dressing room and gave Max and Emme that 'mom' look to reprimand them. She got her kids off the scooters and back into their room."

Crew backstage are believed to have asked the twins to slow down while they were playing. Although Jennifer usually likes to be left alone before she goes on stage, she quickly came out of her dressing room to calm the kids down.

The 43-year-old has insisted her children are always well supervised when she is working.

"Jennifer's family has a private and secure area backstage at each show. Jennifer is a loving and responsible mom, she would never put her children or others in a dangerous situation," a representative for the star told the publication.
