The 29-year-old actress and the 'Body On Me' singer share such a close bond Lindsay treats her as a sibling because they trust one another 100 per cent.

Lindsay - who is currently living in London - always turns to Rita, 25, for advice when she needs it.

The 'Mean Girls' star revealed to The Sun newspaper: "Rita Ora is one of my close friends - I love her. She is like a second sister.

"I have a nice friendship with Rita where if someone just needs to talk, you just trust the person. I can call her like that and she can call me like that."

Lindsay believes she and Rita get on so well because they have have very similar careers with both stars acting and singing.

Rita recently came to Lindsay to ask if she should record the final tracks for her new album while shooting the 'Fifty Shades of Grey' sequels.

She said: "She was asking me if it was a good idea to record her album in her trailer. I said I did it when I was doing 'Herbie: Fully Loaded', but I kind of liked it."
