Too cute! Madonna's twins sing 'Twinkle, Twinkle, Little Star'

Music fills the night at Madonna's house, where twin daughters Stella and Esther are getting some attention.

The 4-year-old girls, whose adoption was announced earlier this month by the pop superstar, showed off their vocal strength in a video posted on Instagram by their mother. The caption accompanying the clip of the girls singing Twinkle, Twinkle, Little Star reads: "A little night Music."

Stella and Esther were adopted from Malawi, the same birth country of Madonna's older children, David, 11, and Mercy, who just turned 11 in January.
