Cameron Boyce And Other Grown Ups 2 Stars Hit Kids' Lemonade Stand

First came the truck loads of electronics, lighting and props.

Then came the crew and cast.

And, finally, came the lemonade.

It was an ideal day to sell lemonade for Maeve Begin and Piper Hall.

The two 9-year-olds plunked down their table and chairs along the sidewalk, under a tree and across the street from the set on Aspen Road Friday afternoon.

They had paper cups and containers of cold lemonade and hung a handmade sign.

The price? A dollar a cup.

The Grown Ups could afford it.

Their customers included Disney Channel actors and returning cast members from the Adam Sandler movie Grown Ups.

Things got a little dicey when a few other young enterprising lemonade sellers with a wagon muscled in on their territory but it all ended well.

13, a singer and actress on the Disney Channel show A.N.T. Farm, bought a lemonade and a Rice Krispies bar from the girls.

, 13, from the Disney Channel show Jessie, also bought a lemonade. He posed for pictures with Maeve and Piper.

Piper looked a bit star struck. Maeve looked ready for the next sale.

They both collected autographs.

Cameron and China were on the set with fellow child actors and returning Grown Ups cast members Jake Goldberg and Nadji Jeter.

Megan Hall said the girls' lemonade stand was a great idea.

They sold lemonade in the shade on a hot day across the street from a movie set.

"And where (else) can you have for a customer," she said.

And Sandler was a customer, coming by for a lemonade after the shoot.
