Benedict Cumberbatch made their first post-pregnancy red carpet appearance at the Golden Globes
Benedict had been nominated at the awards for Best Actor, but lost out on the night to fellow Brit, and friend, Eddie Redmayne. The Sherlock star still managed to make headlines, however, with a hilarious photobomb.
Following on from his famed photograph at last year's Oscars, when he jumped into shot as U2 were having their picture taken, energetic Benedict decided to get in on the action during a little skit between Meryl Streep, Margaret Cho and Michael Keaton.

Margaret was dressed as a North Korean army officer in a nod to her role as a North Korean weatherman on 30 Rock – particularly topical in the wake of the Sony hacking scandal. During a short segment with Globes hosts Tina Fey and Amy Poehler, she requested to have her photo taken with Meryl Streep.
The real highlight of the evening's pictures though wasn't Margaret and Meryl together, or even Michael Keaton on camera duty – but Benedict's photobomb, which saw him leap from his seat to sneak in the snapshot, to the great amusement of the audience.
