Is Katy Perry sending a message to boyfriend Orlando Bloom via a cryptic subtweet?

The 31-year-old "Roar" singer shared a link to Peggy Lee's "Is That All There Is?" on Wednesday night, days after photos of Bloom and Selena Gomez seemingly getting close in a Las Vegas club surfaced online.

The jazz staple may seem like an innocuous enough song choice, but take a look at the lyrics:

"And then I fell in love, with the most wonderful boy in the world.
We would take long walks by the river
Or just sit for hours gazing into each other's eyes.
We were so very much in love.
Then one day, he went away and I thought I'd die.
But I didn't.
And when I didn't I said to myself,
'Is that all there is to love?'"

Bloom, 39, was spotted hugging the 23-year-old "Hands to Myself" singer at LIGHT Nightclub on Friday, though an eyewitness tells ET there was no kissing and they "definitely did not leave together." Another source insists the duo truly are just friends -- "They have the same manager." -- and that things between Bloom and Perry are "great."

"Katy and Orlando are the real deal and are totally in love. We've never seen Katy this happy and so smitten," we were previously told. "They are head over heels for each other."
