Bosses feared the pair would refuse to work together this week after the fiery dancer, 32, stormed off, leaving the 36-year-old model in tears.
Brendan went off into one of his moods and Lisa couldnt understand what shed done, a source tells the Daily Star.
She was devastated, crying and sobbing. It was very harrowing. She was very upset.
Lisa appeared on BBC2s Strictly Confidential to clear the air afterwards.
I couldnt understand what Id done to upset him. I thought he was angry with me but he wasnt, she says.
He did storm off but we have now begun training again and all is OK.
Brendan is said to have also reduced previous partners Kelly Brook, 28, and Natasha Kaplinsky, 36, to tears on the show.
