For the Fourth of July, mother-of-eight Kate Gosselin entertained bodyguard Steve Neild and his family at her $1.1 million home in Wernersville, Pa.

At the pool party/picnic, she mostly hid from photographers. However, the reality star, 35 - who last week denied having any plastic surgery except for a tummy tuck - was snapped briefly prancing around in a skimpy bikini.

"Steve brought his two sons and one of their girlfriends, and they all pitched in, playing with the kids and helping with the cookout," a witness tells "They grilled on the back patio behind the house and made a bonfire in the back horse paddock where they roasted marshmallows and hot dogs. The kids were running around laughing and having fun, playing hide-and-seek."

Meanwhile, her ex Jon celebrated the holiday with his new squeeze Ellen Ross.

They enjoyed breakfast at the Wyomissing Family Restaurant in Wyomissing, Pa., before joining some family members at a Fourth of July parade.

Says a source, "They sat along the street, shared snacks and waved to the passing floats and kids throwing candy. Ellen seemed bored and they both spent a lot of time texting and talking on their phones."

After the parade, they went to Jon's pool and laid in the sun for a few hours before packing up and driving back to Harrisburg to Ross' apartment.
