Little Emme was color-coordinated with her mom in a matching red and white dress.
The four-year-old looked delighted to be playing in the park with her mom and Casper, who scooped the toddler up in his arms and swung her around.
They were all at a charity soccer match and decided to make it a family affair, even bringing Lopez's mother along.
Jennifer, 43, and her beau were spotted looking at diamond jewelry at Tiffany & Co. while doing some shopping in Perth, Australia earlier this month.
As RadarOnline reported, Jennifer celebrated her one year anniversary with boytoy Casper in October.
