On Tuesday, Us Weekly revealed that Johnson dyed her hair back to blonde from the brown hue she was because of Fifty Shades of Grey.

Johnson made her big reveal during Stella McCartney's Green Carpet Collection event during London Fashion Week on Sunday, Sept. 14 with other stars such as Rita Ora and Ellie Goulding at the party. Although her parents probably saw her new hair color, mom Melanie Griffith revealed last month that Johnson wouldn't let her see Fifty Shades when it comes out in theatres next year.

Griffith told Indiewire last month that she probably wont end up seeing the film. "[Dakota] was like, 'You guys cannot come. There's no way.' So we're not going," she said. Although Griffith did admit she visited her daughter on the set.

"I did go visit for a couple of days when they were shooting just normal stuff," the actress said. "I did see the Room of Pain - I did go in there and check it out."

However, Griffith was super proud of her daughter. She called Johnson "amazing" and "so good. It's just so beautiful to see her doing this."

Fifty Shades of Grey will be out Valentine's Day 2015 in movie theatres.
