Carrie Fisher warned Daisy Ridley that appearing in 'Star Wars' would change her dating life forever.

The Hollywood icon - who played the role of Princess Leia in the sci-fi movies - spoke to Daisy about the way stardom would impact her search for love, telling the actress that her personal life was set to become much more complicated.

Carrie - who died in December last year, aged 60, shortly after she stopped breathing on board a trans-Atlantic flight - told Diasy that her love life would become more difficult ''because you don't want to give people the ability to say 'I had sex with Princess Leia'''.

Daisy, 25, also revealed that she and Carrie would spend their time on the movie set discussing the veteran star's battle with bipolar disorder, as well as her use of LSD.

She told Vogue magazine: ''I'd never met anyone openly bipolar before, who discussed loving glitter because of her LSD days.''

Last month, meanwhile, Carrie's daughter Billie Lourd revealed she'd auditioned for the role of Rey before it was awarded to Daisy.

However, Billie explained that her disappointment was somewhat tempered by her being given the part of a Resistance fighter in 'Star Wars: The Force Awakens'.

Billie - whose father is talent agent Bryan Lourd - recently shared: ''J.J. Abrams called me to come in for Star Wars because he couldn't find someone for the lead.

''He ended up finding Daisy Ridley, who's an incredible actress - so talented! But I went in and he ended up giving me this tiny role with a couple lines. I was super excited.''

Carrie will make her final on-screen appearance in the much-anticipated 'Star Wars: The Last Jedi', which is set for release later this year.
