Continuing to share more tributes, Gerber then posted another Story reading: "The only person who wears my face on a sweatshirt", with a picture of the actress wearing a white hoodie that had the model's face and name on it.

"The best protest buddy", the teen wrote in the following post alongside a picture of the two women attending a Black Lives Matter protest in July.

Celebrities including Once Upon A Time In Hollywood’s Margaret Qualley and models Joan Smalls and Georgia May Jagger also paid birthday tribute to Delevingne by sharing photos and messages on Instagram.

"Dear @caradelevingne, man, too much to say. So incredibly lucky to have you as a friend. I love you, happy birthday”, wrote Qualley alongside a series of pictures of Delevngne lying on her stomach and another picture in black and white.

Delevingne has been pictured spending plenty of time with Gerber, Qualley and sister Rainey Qually as lockdown eases.

The Suicide Squad actress split from her long-term girlfriend Ashley Benson in early April, according to People.

The foot tattoo is the latest addition to Delevingne’s growing number of inkings. Known to have over 20, the 28-year-old revealed her first tattoo — lion on her index finger — in 2013.
