Cara Delevingne and her rock star girlfriend St. Vincent were rumored to be engaged after they were spotted wearing matching diamond rings in their recent outings.

The 23-year-old British supermodel and actress was seen with her 32-year-0ld flame at the front row of the Chanel fashion show during the Paris Fashion Week last Oct. 6.

While Cara Delevingne was seen getting cosy with girlfriend St. Vincent, the two caught the eye of many photographers when they wore matching diamond accessories on their fingers.

This prompted speculations that the former girlfriend of Michelle Rodriguez is now planning to tie the knot with the American rock star, The Hollywood Life said in a report.

After their sweet outing, the "Face of an Angel" actress was next spotted in Ingelwood, California with her girlfriend to attend Janet Jackson's concert. The couple was seen entering Chateau Marmont hotel in Los Angeles later in the evening, Just Jared said in a report.

Early this year, the couple hinted that they wanted to marry soon when St. Vincent, whose real name is Annie Clarke, posted an Instagram photo of a handwritten note saying, "Marry me, Annie Clarke."

Fans speculated that it was the handwriting of the "Paper Towns" actress. St. Vincent, meanwhile, captioned the photo with, "Ok."

Cara Delevingne previously talked about her sexuality when she graced the cover of Vogue in July, saying that she learned to accept that she is in love with a woman when she was 21-years-old.

Talking about her latest beau, she said, "Being in love with my girlfriend is a big part of why I'm feeling so happy with who I am these days."

Before Cara Delevingne went public about dating girlfriend St. Vincent, the "Pan" actress was first linked to "Furious 7" star Michelle Rodriguez. The couple's relationship lasted for a few months before they decided to call it quits.
