Star from One Direction's first disc #1 in Latvia (4)
I believe the answer is:
idol
'star' is the definition.
(idol is a kind of star)
'one direction's first disc 1 in latvia' is the wordplay.
'one' becomes 'i' (Roman numeral).
'direction's first' becomes 'd' (lst letter of 'direction').
'disc' becomes 'O' (disc-shaped letter).
'l in latvia' becomes 'l' (I am not sure about this - if you are sure you should believe this answer much more).
'i'+'d'+'o'+'l'='IDOL'
'from' acts as a link.
Can you help me to learn more?
(Other definitions for idol that I've seen before include "Object of worship (or love?)" , "Image of a god (not icon)" , "Graven image or greatly admired person" , "False god" , "Much-loved actor" .)
