Samantha Ronson proposes to Lindsay Lohan

Samantha Ronson proposed to Lindsay Lohan on holiday with a £50,000 ring.

The 'Mean Girls' actress was thrilled when DJ Samantha suggested a civil partnership and presented her with the Cartier diamond band during their break in Mexico.

The lovers were having dinner by the beach in Cabo San Lucas when a waiter came over with the ring which was hidden inside a covered silver tray.

A source at the £1,500-a-night Esperanza hotel told Britain's Star magazine: "Sam brought Lindsay down at 9pm to a huge dining table laid out by the water's edge.

"Sam really went all out and even arranged for a group of Mexican singers to entertain them with songs.

"It was a gorgeous ring with a big diamond that Sam had bought before the holiday. Sam asked her if she would marry her and the waiter popped a champagne cork as Lindsay accepted.

"It was such a beautiful setting with perfect weather and was really romantic." The pair stayed up celebrating with Cristal champagne until 2am before disappearing into their hotel room together.

Lindsay, 22, recently admitted she is very "happy" in her relationship with Samantha.

However, the actress - who has checked into rehab on three separate occasions - doesn't believe her lover is responsible for the changes in her life.

Lindsay said: "People can think what they want. I'm really happy, and that's all that matters. She's a really great person.

"But I think that anything that's change in my life is because of me. I've gone through it and I've had to deal with it and I've made the decision to move forward. So yeah, she's a great person."
