I'm a little stuck... Click here to teach me more about this clue!

'the little boy' is the definition.
'Reg' can be an answer for 'boy'. I'm unsure of the 'the little' bit.

'embraced by more girls' is the wordplay.
'REG' is hidden within the letters.
But, I'm unsure how the hidden word is indicated.
