'Very Happy' Katy Perry Spends the Day 'Laughing' and Playing with Orlando Bloom and His Son Flynn

Katy Perry has met the family.

The singer linked up with Orlando Bloom and his son Flynn, 5, over the weekend, a source tells PEOPLE.

The pair, who have been spotted hanging out several times already this month, "spent all day together" on Saturday.

"They attended a kids' birthday party at Robert Downey Jr.'s house with Orlando's son Flynn," the source says. "Katy even sat in the back of the car with Flynn when Orlando drove them to the party."



Indeed, TMZ posted photos showing the pair riding together in a car, with Perry sitting in the back sipping on coffee.

Perry, 31, and Bloom, 39 – who shares Flynn with ex Miranda Kerr – were first seen mingling at the Weinstein Co. and Netflix Golden Globes afterparty in January, and already look "so happy" together, according to the source.

"They were laughing, playing music and joking around with Flynn," the insider adds of the Saturday outing. "They stayed at the party for hours. Katy looked very comfortable at the kids party. She seemed very happy to spend the day with Orlando."
