After their vacation in Hawaii wrapped up earlier this month, Perry, 31, and Bloom, 39, jetted off to England to “introduce her to friends and family,” a source tells PEOPLE.
“They flew private jet with Orlando’s friends from London to another part of England and then drove all over the place for a week,” adds the source.
At one point during their adventures on Bloom’s home turf, the actor introduced his pop star girlfriend to his mother Sonia, the source says.

The duo returned to Los Angeles on Saturday, when they were spotted at LAX. Bloom spent the next day bonding with his son Flynn, 5 – whom the star co-parents with ex Miranda Kerr – while Perry caught up with pals, the source says.
“Orlando and Katy seem very serious,” another source told PEOPLE in early March. “They have a give-and-take relationship.”
“Katy hasn’t looked happier. She always has the biggest smile when she is around Orlando,” added the insider, who noted Bloom “is a gentleman and dotes on her.”
