As some of you may be aware, Mariah Carey got herself engaged last Thursday to billionaire businessman James Packer, so it's not exactly surprising that she's got a reported whopper of a bauble as a result. Still, twitter is alight with pics of the rumoured ring, although nobody's actually seen it perched on her finger.

Oh, wait, hang on... this might be it. There's a little spec of something on her ring finger there. Squint hard enough you might see it - or stop it from poking you in the eye from over the other side of the Atlantic. 

For those hankering for further details and a close up... It was designed by Wilfredo Rosado from Puerto Rico, and it's HUGE.

As for what it cost? A reported €7million.

Again, congrats to the happy couple - who are both still reportedly technically married to their ex partners. Despite this, Nick Cannon had this by way of felicitations...
