Christie Brinkley is publicly battling her brother while tweeting barbs towards ex-husband Billy Joel's new wife (his fourth). Since the death of their parents, Christie and brother Gregory Donal Brinkley have been at odds over memorial services and the handling of the estate.
As reported earlier in the Inquisitr, even Christie Brinkley's daughter, Sailor, has joined in, tweeting venom towards her uncle.
"Just know not to trust a man who tries to ruin and create conflict on his 17 year old niece's birthday … I don't trust him nor do i trust what he does or what he believes in. I in no way want to be connected to him or his lifestyle," Sailor wrote on Twitter.
