Model-turned-actress Cara Delevingne stepped out at her girlfriend St. Vincent’s concert in Montreal Saturday sporting cotton candy-colored hair. Delevingne’s ‘do’ comes as a surprise, as she is rarely seen straying from her trademark long tresses in natural-looking shades of blonde and brown. The supermodel was joined by her “Suicide Squad” pals Margot Robbie, Jay Hernandez and Joel Kinnaman as she tried to go incognito at the concert

Delevingne, 22, partied with friends by donning a pink wig, a funky purple bandana with a black pattern, and sunglasses. She paired her look with a white cropped T-shirt that had pineapples on it, printed shorts and a denim shirt tied loosely around her hips.

Delevingne 's boxer shorts were emblazoned with the slogan ‘got bacon?’ alongside a printed cartoon bacon motif. The shorts were actually men’s boxers and available online at Amazon, Mirror UK reported. The “Paper Towns” actress showcased her eye-catching bright pink wig with her ensemble during Osheaga Festival in Montreal, Canada.

Meanwhile, Margot Robbie joined in the fun by donning her own disguise. The Australian actress opted for a more natural look, however, sporting a black wig and red lipstick.

Delevingne appeared to be enjoying a much needed break after a hectic week of promoting her new film. She came under criticism for appearing to be “in a mood” and “sarcastic” when interviewed on “Good Morning Sacramento.” “I am soooooo lucky and anyone who thinks I am unappreciative or ungrateful clearly doesn't know me,” the model told her 3.29 million Twitter followers.

The British beauty showed her relationship with musician St Vincent aka Annie Clark is stronger than ever as she partied at the concert. The couple were thought to have split earlier this month after eight months of being together, but they silenced rumors by stepping out to attend the New York premiere of her film.

Meanwhile, the actress said in a recent Hollywood Reporter interview she is not leaving modeling, or retiring, in the wake of her parting ways with the Storm Model Management agency. Delevingne said she has supporters in the fashion industry too in the form of Karl Lagerfeld. “He’s always known that I’ve wanted to act. He was very nice to put me in his fashion film,” she said.
