Cleo's special edition of Alien (5)

I believe the answer is:

laine

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

'cleo's' is the definition.
(English singer Cleo Laine)

'of alien' is the wordplay.
'of' indicates an anagram (the answer comes from or 'of' the letters).
'alien' anagrammed gives 'LAINE'.

'special edition' is the link.
I am not very happy about this link. Some or all of it may belong to another bit of the clue.

Can you help me to learn more?

(Another definition for laine that I've seen is " Dame Cleo --, jazz musician".)

I've seen this clue in the Evening Standard.
