The pregnant star presented her last GMB on Thursday morning (22 January) and is now on maternity leave awaiting the birth of her first child.
So far, she hasn't revealed whether it will be a boy or a girl but that didn't stop her colleagues trying to guess!
Doctor Hilary predicted a boy because of Charlotte's neat bump, while Laura Tobin did the ring test and decided it would be a girl.
"I genuinely, genuinely trust and believe that I know the answer, there's the ring test… I'm going to take Charlotte's wedding ring - I've done this five times with my friends and it has come right every single time," said Laura.
Laura continued: "You tie the mother-to-be's wedding ring on a piece of string and you hang it over the baby bump. If it spins in a circle it's going to be a girl and if it swings backwards and forwards it's going to be a boy."
Charlotte kept tight lipped!
The presenter was given balloons and a cake shaped like a nappy … let's hope that tastes better than it sounds!
"I just want to say thanks so much to all you [to the team] and and all of you [the viewers] for the good wishes that you've sent me," said Charlotte. "I'll be back before you know it honestly!"
Charlotte announced her pregnancy in August. It will be her first child with husband Mark Herbert.
