Charlotte Crosby has taken to Snapchat to show off her impressive diamond ring from Stephen Bear . Flashing the sparkler, the former Geordie Shore star gushed in that she “will never get over how astonishing this ring is”.Just last week, Bear got down on one knee in front of his reality star girlfriend in the middle of Sydney Harbour.The lovebirds have been in Australia and New Zealand as part of their promotional tour for their MTV show Just Tattoo Of Us.Charlotte Crosby showed off her diamond ring (Photo: Snapchat)Bear presented her with the ring on a recent holiday (Photo: Snapchat) They’ve only been seeing since the start of this year, yet already Stephen Bear and Charlotte Crosby have talked engagement rings, marriage and lots of babies. And to mark the occasion, Bear decided to get Charlotte’s heart racing on their way to dinner.Bear made a rather special gesture in front of Charlotte (Photo: xxxxxx/snapchat)But how did she react? (Photo: xxxxxx/snapchat)Taking to Snapchat after the event, Charlotte explained absolutely what happened.”Stephen thinks it’s comical to get down on one knee in the middle of Sydney Harbour,” she told the camera.”Everyone’s staring, thinking he’s going to propose.”And all he does is hands us a chewie.”He got down on one knee by Sydney Harbour (Photo: xxxxxx/snapchat)But then decided it was just a prank (Photo: xxxxxx/snapchat)She rolled her eyes and signed, before panning the camera over to a not-even-slightly-sheepish-looking Bear.It’s not the 1st time Bear and Charlotte have raised eyebrows with their talk of engagement. When they were on holiday in the Dominican Republic last month, Bear surprised his lady-love with a massive diamond ring.”Stephen surprised me with a huge diamond ring while we were around the pool,” Charlotte explained later.”I’d seen it in the jewellery shop in the hotel yet it was far too expensive.” But while the flashy gift wasn’t quite a sign of things to come, the couple have now got matching fish tattoos on their fingers .
