Cara Delevingne & Girlfriend St. Vincent Catch a Flight Together!

Cara Delevingne and her girlfriend St. Vincent arrive at Heathrow Airport together on Monday (December 14) in London, England.

It looks like the 23-year-old model and St. Vincent, 33, are still going strong — they were last seen out together in mid-November.

Cara is set to begin working on the highly anticipated movie Valerian and the City of A Thousand Planets next month in Paris, France.

Rihanna, Dane DeHaan, Ethan Hawke, and more are also set to star in Valerian, which will be released on July 21, 2017.
