You don't just walk around with a giant-ass diamond on your ring finger and not expect people to jump to conclusions, Katheryn.

Perry and Bloom have been dating since the start of the year, which makes all this seem a little fast, but then it wouldn't be the first marriage for either of them and when you know, you know, you know?

The pair were spotted around New York on Monday night and Perry had a massive yellow diamond hanging off her left ring finger, sparking all sorts of rumours that they are secretly engaged.

ET are claiming an eyewitness said: "She walked with her left hand leading her, and bent her hand to show off the large sparkler to the cameras."

Said ring is a massive oval cut yellow diamond surrounded by smaller baguettes, but as you'll notice up top, the same finger was conspicuously vacant at last night's 12th Annual UNICEF Snowflake Ball Honoring UNICEF Goodwill Ambassador Katy Perry and Philanthropist Moll Anderson, at which Perry was presented with the Audrey Hepburn Humanitarian Award by none other than Hillary Clinton.

So we're either being trolled or they're keeping it on the DL, but either way they're happy so what difference does it make to us.
