Orlando Bloom and his son Flynn had some fun playing in Central Park in New York City on Sunday. The duo stopped for an ice pop and hung out on the swings on the hot and sticky day. Flynn's mother, model Miranda Kerr, was nowhere to be seen.

Also over the weekend, Gwen Stefani enjoyed the sun at Malibu beach with her children Zuma Nesta Rock and Kingston. The singer protected her porcelain complexion by staying underneath an umbrella (see photos on the following pages).
