Petra Ecclestone arrived at the High Court today for the latest round of her legal battle with ex-husband James Stunt following their £5.5billion divorce.
The 29-year-old was supported in London this morning by her sister Tamara, who had earlier told her on Instagram: 'Hey little fighter, soon things will be brighter'
Petra found herself embroiled in a messy divorce battle with her ex-husband Mr Stunt, which has been claimed to be one of the most expensive in British history.

But Petra, 29, is now moving on from her split and has won praise from her older sister Tamara, 33, who claimed she is 'so proud' of her sibling.
The Formula One heiress posted a tribute to her little sister on Instagram at about 9am, in which she admired Petra's 'unimaginable strength, dignity and composure'.
Mother-of-one Tamara shared a telling quote with her followers on the photo-sharing website that read: 'Hey little fighter, soon things will be brighter.'
Alongside it she made reference to Petra, saying: 'You may be my little sister, but you have shown unimaginable strength, dignity and composure. Proud of you.'

Tamara won praise from her fans, who admired how 'supportive' the socialite had been towards her loved one, with one commenting: 'Beautiful words.'
Petra, who shares three children – sons Andrew and James and daughter Lavinia – with her ex-husband, divorced Mr Stunt last October.
But her sister Tamara has been a constant support to her throughout the difficult proceedings.
