while I do agree that she has every right to express it, and even though some people thought it was low to publicly dump Tully without her knowledge i could understand where she was coming from and that she really didn't have much of a choice...
she now does have the chance to spit whatever insults (and i bet theres heaps) directly at Tully rather than everyone else, but chose to do it publicly
i just think knowing what the reaction was at her last tweet this one could possibly have been a calculated move, which in that case she has definitely succeeded because her tweets have gotten more of a reaction that what Tully actually did
