Maddie Moate, presenter of CBeebies show Do You Know? is engaged to BBC star Greg Foot.
The 24 year old revealed that her boyfriend popped the question while in Thailand.
Showing off her unusual ring, Maddie announced the news with an excited picture from the beach.
“The time we got ENGAGED! Yep, whilst we were in Thailand @gregfoot popped the question and of course I said yes,” she wrote on Twitter.
“It’s been an incredible few weeks enjoying our engagement as a couple, but now feels like the right time to spread the word!”
She displayed a golden coloured stone, which appeared to resemble an acorn, on a thin band for the camera.

Greg, known for being the Science Guy on Blue Peter and presenter on the YouTube show BBC Earth Lab, also shared the message.
“WE GOT ENGAGED in Thailand and didn’t tell anyone for ages (which was wonderful) and decided it’s now time to go public.”
Fans were quick to comment on the couple’s happy news, though some parents admitted their children may be upset.
“My (4 year old) son will be devastated,” one fan wrote.
Another added: “I was thinking the same of my 3yo. Seriously though, congratulations to you both, may you be blessed with a long and happy marriage.”
“How lovely! My 4 year old will weep when I tell him, I’m sure he thought he was going to marry you,” a third wrote.
