Hollywood actress Halle Berry has won a court battle to prevent her ex-boyfriend from making their daughter 'look more white'.

According to TMZ, the 48-year-old Monster's Ball star took legal action after Gabriel Aubry attempted to alter six-year-old Nahla's appearance by straightening and highlighting her hair.

Although French-Canadian model claimed he simply wanted to tame the little girl's natural-curly locks, Berry accused him of trying to hide her African-American roots.

During the court proceedings Berry's lawyer Steve Kolodny claimed that the Oscar-winner was left fuming and is convinced that Aubry is determined to make Nahla "appear" white.

In court documents berry also states that Aubry had caused Nahla "potential psychological and physical damage" - and could cause her to wonder 'why her natural appearance is not good enough".

"I strongly feel that Gabriel's same underlying attitude is at the root in the changes which only he could have been causing to our daughter's hair," her testimony read.

A judge has since ruled that neither parent are allowed to change Nahla's hairstyle.

The hearing is the latest drama in the former couple's bitter custody battle following their split in 2010.

At the height of their ongoing feud Berry, who is now married to Olivier Martinez, accused Aubry of using the N-word. In 2012, Berry was banned from moving with Nahla to France, where she said they would have more privacy. Aubry and Martinez were also involved in a violent altercation over the Thanksgiving holiday.
