Entertainer’s routine including leading pairs from Rome ballet (7)

I believe the answer is:

acrobat

'entertainer's' is the definition.
(type of circus entertainer)

I can't explain the rest of the clue.

(Other definitions for acrobat that I've seen before include "circus artiste" , "flipper" , "Spectacular gymnast" , "Performer of great agility and coordination" , "Tumbler" .)

I've seen this clue in The Times.
