While Emme was content to sit beside her mom and smile quietly, Max decided to be a little more rambunctious, and wander around the stage, eventually hiding in the side-table between the interview chairs, which DeGeneres usually has people jump out of to scare her guests.
As Max climbed into the box and closed the lid, his sister couldn't help but laugh while Lopez appreciated the calm.
"Maybe you should get one of these at home," DeGeneres quipped.
"Yeah, to keep him nice and quiet. This is the quietest he's been in nine years," the Shades of Blue star joked.
The twins also helped their mom compete in a dance-themed game against her fellow World of Dance judge Derek Hough!
"It's very simple. I was having lunch somewhere and I saw him as he passed by," Lopez said. "Afterwards I went outside and for some reason I felt like tapping him on the shoulder."
Lopez said that they first started chatting about living in Los Angeles, as Rodriguez just moved to California after living on the East Coast for years. Eventually, he reached out to ask her on a date.
"He texted me, said, 'Let's go out to dinner,' and I said, 'OK,'" Lopez recalled, laughing at the simplicity of it all. "We had a nice dinner."
