Cheat bedding former lover, sordid practice? (7)

Ross

I believe the answer is:

sexting

'sordid practice?' is the definition.

'cheat bedding former lover' is the wordplay.
'cheat' becomes 'sting' (sting is a kind of cheat).
'bedding' is an insertion indicator.
'former lover' becomes 'ex'.
'sting' enclosing 'ex' is 'SEXTING'.

(Another definition for sexting that I've seen is " phone's billets- doux?".)

I've seen this clue in The Guardian.
