Madonna's twins too cute for words

The 58-year-old singer posted a video of 4 year-old Stella and Esther on Instagram after they were caught singing Twinkle, Twinkle, Little Star.

Madonna hit the headlines earlier this year when she denied rumours that she was heading to Malawi to adopt - reports that later turned out to be accurate.  Shortly after her 'holiday' in Malawi the news broke that she has in fact adopted the two toddlers.
