Girls gee you up flagrantly (11)

Ross

I believe the answer is:

egregiously

'flagrantly' is the definition.
(thesaurus)

'girls gee you up' is the wordplay.
'up' indicates an anagram.
'girls'+'gee'+'you'='girlsgeeyou'
'girlsgeeyou' anagrammed gives 'EGREGIOUSLY'.

I've seen this clue in The Times.
