IF you thought you'd seen it all on the JUSTIN BIEBER merchandise front, you were wrong.
The teen titan has cornered a previously uncharted market with the launch of his very own singing toothbrushes.
The electric scrubbers will come in two designs - one plays Biebs' hit tunes Baby and U Smile, while the other blasts out Somebody To Love and Love Me.
Each song lasts two minutes - the recommended length of time for a teeth-brushing session.
The £6 personal hygiene appliances from Ashtel Dental will launch on July 1.
Other Bieber-themed oral care products by the company include an adult toothbrush, floss and travel kit - which includes a mini hourglass timer and a tongue scraper.
Cotton wool for parents' ears would have come in handy too...
