Celebrity photographer Terry Richardson uploaded a photo on his blog which sees the singer showing off a ring on her engagement ring finger.
"Gaga showing off her new engagement ring!" his blog post reads.
Lady GaGa has yet to confirm or deny whether the ring is an announcement of her engagement.
The star has been romantically linked with Vampire Diaries actor Taylor Kinney, but reports recently claimed that they have broken up.
She worked with Terry Richardson for a hardback book of photographs titled Lady GaGa X Terry Richardson last year.
Lady GaGa recently said that her current Born This Way Ball shows make her throw up.
