Brooke and Helen played sisters Sophie and Rosie Webster together for eight years, until Helen left in 2012.
Speaking to The Sun, Brooke recalled some of the most memorable times from when they were working together.
She revealed that when they were filming on location in Paris, she and Helen had very different ideas of how to spend their breaks, saying: “We had 20 minutes’ break before going home.
“I ran to McDonald’s and Helen went to Chanel. She’s a character. I love her. We speak all the time. Helen is absolutely bonkers, but there’s not a mean bone in her body.”
While insisting Helen isn’t a bad person, she did admit that she is a diva. Brooke said: “She’s such a drama queen. I shared a dressing room with her and Tina O’Brien and it was an absolute pigsty.
“Filthy, with clothes all over the place and cushions, rugs, jewellery, quilts, laundry everywhere.
“I walked in one day and Helen was screaming and shouting, throwing everything outside and wailing, ‘How could we live like this?’ Tina and I walked away and when we came back, the room was spotless and empty.
"Helen had taken her stuff and set up camp in the Visiting Artists room with every bit of mess, as it all belonged to her. It was hilarious.”
