Bradley Cooper was displaying a rather nasty bruise on his arm during a motorbike ride on Thursday.
The Hangover star showed the painful-looking mark on the inside of his elbow stretching up underneath his grey T-shirt as he rode around Los Angeles.
It is not known how the 39-year-old actor got his injury but he seemed not bothered by the bruise during his day out.
Bradley was without his model girlfriend Suki Waterhouse who was busy partying in London with her model friend Cara Delevingne.
She looked typically stunning in a baby pink dress, white tights and heels, and spent much of the evening larking around with renowned party animal Cara at the Harrods and Karl Lagerfeld Parfums VIP dinner in London.
However, Suki was on hand to join Bradley at the Oscars earlier this month where he lost out in the Best Supporting Actor category to Jared Leto.
Cooper was nominated for his role of FBI Agent Richie DiMaso in American Hustle.
He will next star alongside his Silver Linings Playbook co-star Jennifer Lawrence in depression-era film Serena.
The film is based on Ron Rash's 2008 novel about a North Carolina timber baron and his ambitious wife and explores her descent into madness.
