Prince Harry's rumoured girlfriend Meghan Markle may want to delve into the British history books if this test is anything to go by.
The 33-year-old Suits actress, who is rumoured to be dating flame-haired bachelor Prince Harry, was quizzed earlier this year on her knowledge of British culture and she failed miserably.
During the quiz, which was aired on UKTV, Meghan admitted she was the "worst" person to have ever played the game.
The brunette beauty was able to correctly pinpoint three British ales but when asked what the British term for 'sidewalk' is she couldn't answer despite visiting her 32-year-old beau and his father the Prince of Wales earlier this year at London's Kensington Palace.
When she was asked which spread British people prefer - Marmite or Vegemite - the brow-haired actress replied “easy Vegemite” straight away.
However of course, Marmite is the much-loved spread in the UK.
Speaking about the test, the 'Suits' actress said: "I think I lost. I think I was the worst at this game."
She was also quizzed on her knowledge of Cockney rhyming slang, when she was asked what 'apples and pears' meant.
Meghan couldn't even guess the answer, which all British people will know is slang for stairs.
Despite Meghan's lack of British knowledge, it has been reported she is making Harry - who ended his relationship with his former girlfriend Cressida Bonas in 2014 after their two year romance - the happiest man he has been "for many years".
A source told the Mail Online: "He's happier than he's been for many years. He's in a very relaxed period of his life and Meghan has come along at the right time."
Although Meghan has brightened up Harry's life, her half-sister Samantha Grant has warned Harry against his new girlfriend because she claims she can't be trusted.
Samantha - who shares the same father, Thomas Markle, as Meghan - branded her sister a "shallow social climber" who always wanted to be a princess and is "narcissistic and selfish".
Speaking previously the mother-of-three writer said: "The royal family would be appalled by what she's done to her own family. The truth would kill her relationship with Prince Harry, he wouldn't want to date her any more because it puts her in a bad public light.
"I certainly don't think Harry or his family would want to associate with her afterwards."
