Is Cara Delevingne set to walk down the aisle? Supermodel seen 'down on one knee with girlfriend St Vincent in Paris' 

Cara Delevingne has been looking happier than ever since she started dating singer St Vincent 11 months ago.

However, a new report claims the supermodel may be ready to take things to the next level as she was apparently seen proposing to the American star in Paris.

The model-turned-actress, 23, got down on one knee at the top of the Eiffel Tower, according to fellow tourists in the City of Lights.

An eyewitness told The Sun: 'There are two lifts going up the tower and they were in the one ahead.

'As my group got out of the lift I could see Cara on bended knee, clearly proposing to her girlfriend.

'It was really touching. Cara obviously likes to do things traditionally.'

The tourist added it wasn't clear if Cara was joking or was serious.

If Cara did propose, she'd be following in the footsteps of Hollywood stars Tom Cruise and Katie Holmes, who got engaged at the Eiffel Tower back in 2005. 

St Vincent, real name Annie Clarke, and Cara have been dating since March 2015 and have made several public appearances together.

In October, the pair were spotted matching rings on their wedding fingers at Paris Fashion Week.

MailOnline has contacted Cara's representative for comment. 

Cara spoke about her sexuality in an interview with Vogue last year, admitting she was attracted to both men and women.

She said: 'It took me a long time to accept the idea, until I first fell in love with a girl at 20 and recognised that I had to accept it. But I have erotic dreams only about men.

'If I ever found a guy I could fall in love with, I’d want to marry him and have his children.'

However, she was forced to speak out after the interview to insist her sexuality was not 'a phase' after the Vogue writer suggested her parents were unconvinced.

She clarified: 'My sexuality is not a phase. I am who I am.'

Prior to Cara's romance with St Vincent, she had a high-profile fling with Fast & Furious actress Michelle Rodriguez.
