The 30-year-old actress is about to appear in the forthcoming movie 'Mission: Impossible - Fallout' alongside Tom Cruise, but she has admitted she still doesn't realise the extent of her career because she barely gets recognised when she's out.

Speaking to Marie Claire magazine, she said: "It is a weird feeling. I definitely don't feel it yet. I've been lucky because I barely get recognised."

The blonde beauty thinks it helps that she keeps her relationship with her boyfriend Callum Turner "private" because people aren't interested in the details.

She explained: "I keep my relationship super private. He is just completely wonderful and he's my best friend, so that's... I guess you can either choose to talk about it or not. If you talk about it, it becomes interesting to people, but if you don't, then it's not."

Vanessa found herself in the headlines earlier this year when fans began to speculate that she was dating Tom after they were spotted sharing a smooch on the film set.

She said: "Even though the [film] crew were there, it was all like: 'The next wife falls at his feet.' The most disconcerting thing was the people I didn't think would believe it, did, and they were texting my boyfriend, asking: 'Are you OK?'

"I don't think they believe anything they read now because you just can't. None of it is real. To be getting married to him? Not even a snog, it was marriage."

Meanwhile, Vanessa is best known for playing the late Princess Margaret in 'The Crown' and she admitted she wishes "so much" that she could get drunk with Queen Elizabeth's younger sister.

She said previously: "She'd be really fun. She was the coolest person."

Vanessa immersed herself in researching the life of the princess when she landed the role in the Netflix series and one of her favourite stories was of Margaret having a toilet built as a throne.

She gushed: "When I thought was brilliant."
