Jennifer Lopez's kids are all grown up! While sitting down with Ellen DeGeneres on Monday, the "Chegaste" singer brought along her adorable 9-year-old twins, Max and Emme. Since she and ex-husband Marc Anthony welcomed their kids in 2008, the world has gotten a few glimpses of them here and there, but their appearance on Ellen marks their talk-show debut. While Emme was ready for the spotlight and immediately jumped into her mom's lap, little Max preferred to hide behind her chair and later hopped in the fake coffee table Ellen usually uses to scare people for some alone time. Talk about a case of the Mondays.
