Britney and Jamie Lynn Spears were by a pool in Miami with children who were presumably there's, but you never know in that family. They are crazy enough to just pick up kids wandering around and have playtime. I can just imagine Jamie Lynn talking to her sister and being all, "Ok, you're gonna grab that kid and I'll grab this one and we'll toss'em in the pool. Whichever one gets to the other side first wins." "You know sis," Britney would say, "that's the smartest idea you've had since you said I should start dating my backup dancers." Then they both ate barbecue and had a ho-down and did other stereotypical southern things, like let their real children cuss-up-a-storm.
