Never one to keep anything to herself, KIIS 1065 host Jackie "O" Henderson revealed that Sam Frost has done the unthinkable.
"Sam Frost has still not unblocked me, I don't know what I did," she told Sophie Monk who was standing in for Kyle Sandilands on Friday morning.

It comes despite Jackie believing they were on good terms. Jackie also posted a gushing tribute to the Home And Away star back in October 2015.
Jackie captioned a shot of the pair in the KIIS studio as "#girlcrush" along with heart emojis.
Love Island host Sophie revealed that fellow Bachelorette Sam had "unfollowed" her, much to her surprise.
"She used to follow me, that was one of them who's unfollowed me. I don't know what I've done wrong," Sophie said.
She added that a number of celebrities and fashion designers had also unfollowed her during a recent scan of her Instagram account.
"Most of them have unfollowed me. It really hurts your feelings, because you ask yourself, 'What am I doing wrong?' because my content is good," Sophie added.
Jackie also revealed that Gabi Grecko, the ex-wife of Geoffrey Edelsten, had also blocked her, but she believes it has something to do with something Kyle has said about the busty American.
"Kyle doesn't have an Instagram and so I feel like if he ever says anything I get the fall out from it... What have I done to Gabi Grecko ever?"
