Katy Perry and Orlando Bloom continued to fuel relationship rumors Saturday. They took Bloom’s 5-year-old son Flynn to a birthday party and spent the whole afternoon together.

Insiders dished that the trio spent several hours bonding. “They were laughing, playing music and joking around with Flynn,” a source told People. “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.”

TMZ has photographs of Bloom, Perry and Flynn on the way to the party, which was thrown for “Iron Man” actor Robert Downey Jr.’s son, Exton. Perry, 31, was in the back seat with Flynn, and Us Weekly said kept him entertained during the long drive. However, this doesn’t mean she is ready to be a stepmom yet. (Flynn’s mother is Bloom’s ex-wife, Miranda Kerr, a model.)

“She’s having fun with Orlando,” a source told Us Weekly. “I don’t think she’s seeing this as long term yet. It’s a fun hookup thing right now.”

The “Dark Horse” singer also stepped back to allow the “Pirates of the Caribbean” actor, 39, to have quality time with his son. “Orlando was really focused on Flynn and walking around the party holding his hand,” the source said. “Katy stayed behind them most of the time and let them do their thing.”

Both the singer and the actor are frequently the subjects of dating rumors. At the end of 2015, Perry was supposedly seeing her ex John Mayer again, while Bloom was purportedly having a fling with model Kendall Jenner.

Bloom and Perry sparked the latest romance rumors last month at a Golden Globes Awards show afterparty. They were photographed dancing together and smiling. Since then, they’ve been seen together multiple times during dinners and at theaters. Just Jared reported they even held hands after leaving a restaurant last week. However, the two celebrities have not confirmed their relationship status yet.
