Katy Perry and Orlando Bloom just took their relationship to the new level.
The stars are now sharing secret sleepovers, RadarOnline.com can exclusively reveal.
A source close to the pair said that Bloom, 39, has invited the stunning singer, 31, to spend the night when he has custody of his Flynn, his 5-year-old son with ex-wife Miranda Kerr.
"Katy has been bonding with Flynn, and even staying over at Orlando's house when he has Flynn," an insider told RadarOnline.com. "He stays at her house when he doesn't have Flynn."
Bloom has been acting affectionate outside of the home, too. When he and Perry took Flynn to Robert Downey, Jr.'s Malibu home over the weekend, he introduced her to pals.
"He was introducing her as 'my Katy'", the source revealed.
And earlier this month, they attended a producer's Hollywood dinner together.
