Gwyneth Paltrow threw her son Moses a Superhero-themed 3rd birthday party Saturday afternoon.
At the backyard fete -- held at the actress and Chris Martin's $28 million rented L.A. home: Paltrow's ex beau Ben Affleck and Violet, 3, who is a classmate of Apple, 4.
Liv Tyler and her son Milo, 4, John Favreau's family, Steven Spielberg and Moses' grandma Blythe Danner were also there to celebrate the guest of honor, who dressed in a Batman costume.
The backyard was decorated with balloons in the shape of dogs, cows, horses, pigs and zebras. Kids played with hula hoops, goofed around with balloon swords, ate candy and rode horses in the yard. Paltrow also hired two lifeguards in case guests wanted to swim.
Everyone went inside a colorful tent to watch Moses open presents. Afterwards, they snacked on birthday cake and cupcakes.
When the party was over, the guests chanted "hooray, hooray, hooray!" Paltrow walked all the kids to the front yard and spilled candy and Glow Sticks from a car pinata on the deck, which the kids scrambled to pick up.
Tyler was the last person to leave the party at 7 p.m.
