Sharon Osbourne suffered a dental malfunction when her tooth fell out during a live taping of her show The Talk.

The 62-year-old was in the middle of gushing about rocker husband Ozzy at the beginning of the talk show when she realised her front right tooth was coming loose, telling the panel: “My tooth is falling off!”

According to E! online, the feisty TV host joked: “I spent a bloody fortune to f***ing prevent it from falling out. Seriously, does anyone have any glue?”

The rest of the talk show panel – Julie Chen, Aisha Tyler, Sara Gilbert and Sheryl Underwood – looked on as Sharon attempted to put her gnasher back in position.

With no dentist rushing to help, the flame-haired TV personality continued on with the rest of the show with her tooth precariously re-inserted, chatting to Friends actress Lisa Kudrow while covering her mouth with her finger.
