Most people's first kiss is typically a pretty nerve wracking experience - you're trying to not smash your heads together, hoping there's nothing stuck in your teeth and that it won't be too sloppy.
So, spare a thought for Love Actually star Olivia Olson, who had the added pressure of an entire camera crew, film directors choreographing the smooch and the knowledge that millions of people would watch it. Sheesh.
Take a look here:
The American actress was just 10-years-old when she scored the role of Joanna Anderson in one of the most popular Christmas films of all time, which was released back in 2003.

She was cast as the adorable schoolgirl - with an incredible set of pipes - who Thomas Brodie-Sangster's character, Sam, had a crush on in the Richard Curtis classic.
Olivia memorably belted out Mariah Carey's festive tune All I Want For Christmas Is You while Liam Neeson's lovesick son is going to town on the drums.
The scene-stealer had such an extraordinary voice that director Curtis admitted he had to ask her to sing badly as he feared that viewers might not believe a child could have that much talent.
Olivia has obviously watched Love Actually thousands of times - but she only let's her mum put it on over Christmas when she is 'drunk enough'.

To be fair, who would want the whole family to relive your first kiss on a loop every single year?
The actress confessed she had a 'little bit of a crush' on her then-12-year-old co-star Thomas, so she was quite apprehensive about going in for the kill in that airport scene.
Olivia is iconically chased down in the airport by her baby-faced beau, who leaves several security guards in the dust while he races to give her a goodbye kiss.

She discussed how she was in full blown puppy love with Thomas in an interview with Fabulous in 2020, while casting her mind back to her first ever kiss.

The 31-year-old said: "We were kids, I wouldn’t say there was any romance, but that was my first time kissing a boy ever.
"It was weird. There were definitely feelings there of anticipation, like, little kids’ nerves."
Olivia admitted she was even more apprehensive about the kiss 'because she was taller than him'.
Although Love Actually fans might have hoped the two child stars may have got together in the future in real life, it turns out the onscreen couple didn't even keep in touch.

The actress said she 'didn't have a phone or email address at the time' so couldn't swap details with her film crush - making the airport scene where they said goodbye that much more special.
But Olivia has admired Thomas' acting prowess in Netflix's The Queen's Gambit and gave his American accent her stamp of approval.
She went on to reveal that Love Actually was actually filmed backwards, so the airport scene was the first thing she shot.
Talk about being thrown in the deep end alongside some of the biggest movie stars on the planet.
However, Olivia ran into another issue because it was filmed this way - she kept losing her baby teeth and the wardrobe department was running out of ideas.
She explained: "I kept losing my baby teeth, since we filmed so much of the film out of order, by the time we did the singing scene which was a close up of my mouth they were like ‘Ah, can you please stop losing teeth’ because the continuity was out the door.
"I think I lost like three or four teeth on the set which was wild."
The crew had to tactically film Olivia from certain angles to avoid showing her missing pegs, which proved extra difficult while she was hitting Mariah's high notes on stage.
