She shouted: "I'm going to die" after hosts Ant McPartlin and Dec Deonnelly announced the result of the first public vote.
"You can do this", mum-of-two Jane reassured Grace, as she held her face.
"Just focus. Focus."
Becoming overwhelmed with the thought of tackling Vile Volcano, Grace's eyes filled with tears as she admitted: "I don't know why I'm crying."
Jane replied: "You'll be fine, you'll be fine, darling. Trust me.
"Listen, if you don't get a single star it doesn't matter."
Grace became a target after high-pitch screams when she panicked trying to find a key in amongst cockroaches.
Dec said on ITV2's spin-off show I'm A Celebrity... Unpacked: "That was the moment the Great British public collectively decided she should do the trial."
Ant predicted he and Dec would have to be on hand to wipe away tears and give Grace a cuddle as they supported her through the Bushtucker Trial.
They left the Unpacked show to meet the campmate for Vile Volcano.
Meanwhile she remained back at camp being supported by Jane who is her fellow Loose Women panellist.
Jane first appeared on the ITV daytime show in 1999, with Grace joining earier this year - although the pair have not yet starred on the same episode.
I'm A Celebrity continues on Monday at 9pm on ITV.

Alan Halsall - The actor, known for playing the long-running role of Tyrone Dobbs on ITV soap opera Coronation Street, was originally signed up to head Down Under last year but an operation threw his scheduled appearance off-course.
