It's the most romantic time of the year, and although most people are well versed on Valentine's Day rituals, it can help to take inspiration from some of the world's most high-profile celebrity couples.

And who could forget the kiss to end all kisses - that moment when the Duke of Cambridge brushed his bride's lips, marking the beginning of a royal romance whose next chapter includes a baby.

Here, we take a look at some of the stars' most tender moments.
