She is better known for her roles in classic British films, but last night Emma Thompson let her hair down to photobomb actress Lupita Nyong’o (scroll to see video).
Taking a leaf out of Jennifer Lawrence's book, Thompson crept up behind the 12 Years A Slave actress to pull a funny face as she was having her photograph taken at last night’s Screen Guild Awards.
But Nyong’o, who went on the win Best Supporting Actress at the ceremony, was quick to laugh off Thompson’s prank and the two embraced on the red carpet.
Thompson was nominated at the Screen Guild Awards for her leading role in Saving Mr Banks, which sees her star alongside Tom Hanks.
The actress was pipped to the post by Cate Blanchett who took home the award, and now looks more likely than ever to pick up the Oscar in March for her performance in Blue Jasmine.
American Hustle won the top honour at the ceremony, taking home the Outstanding Performance by a Cast in a Motion Picture award.
Matthew McConaughey and Jared Leto also both won for their performances in Dallas Buyers Club, in which they play AIDS patients trying to smuggle drugs across the Mexican border in the Eighties.
1/8 Aaron Paul breaks bad on Bryan Cranston
At the Primetime Emmy Awards in September 2013, Aaron Paul photobombed his Breaking Bad co-star Bryan Cranston - the juxtaposition between Cranston's suave and Paul's joker is wonderful. Top points for photobombing skills!
2/8 Jennifer Lawrence the Golden Globes monster
She may have won the Best Supporting Actress award at the Golden Globes in January 2014 but American Hustle star Jennifer Lawrence hit more headlines for this classic red carpet photobomb. As singer Taylor Swift was being interviewed, Lawrence snuck up behind her, joking that she was coming to 'push (Swift) down the stairs'.
3/8 Emma Thompson does a Jennifer Lawrence
Taking a leaf out of Jennifer Lawrence's photobombing guide, British actress Emma Thompson pulled a funny behind 12 Years a Slave star Lupita Nyong'o at the Screen Guild Awards in January 2014. Nyong'o laughed when she realised the prank and the stars hugged.
4/8 Frog ambushes NASA mission
One giant leap for frogkind! This little froggy ended up being blasted into space when a rocket took off from Virginia in September 2013. It is unknown whether the frog survived his ordeal, but it sure made for a good photobomb.

5/8 Will Self takes the Booker spotlight
'Umbrella' author Will Self held up his book in an umbrella motion after losing out on the Booker Prize to Hilary Mantel in October 2013. Safe to say he somewhat dominated the photo and rather overshadowed Mantel - funny though.
6/8 George Clooney lowers the tone an oh-so-serious event
Not content with his film star looks being pushed to the background of any photo, George Clooney photobombed Steven Spielberg, Jessica Seinfeld and Jerry Seinfeld at the USC Shoah Foundation Institute 2013 Ambassadors for Humanity gala in October 2013.
7/8 Zach Braff the wedding crasher
The former Scrubs actor was spotted grinning cheekily behind a bride and groom in front of Times Square in November 2013. Wedding photographer Sascha Reinking noticed and tweeted Braff: 'Sir, I think you photobombed my newlywed couple the other day in New York :). Well played...'
8/8 Great white shark creeps into holiday snap
This ominous image was posted to Facebook in December 2013 by the mother of one of the two boys seen here surfing in California. June Emerson only noticed the suspected great white shark when going through her holiday photos at home. She didn’t want the boys to be put off swimming in the sea, so told them it was a dolphin when they saw the picture.
