Could they look any happier?

After watching their wedding on Saturday, it's safe to say that people are besotted with the love story that is Prince Harry and Meghan Markle's relationship. The couple held hands practically all day and stared at each other with complete adoration for most of the wedding ceremony and today, we saw the full force of that love yet again.

The newlyweds attended Princes Charles 70th birthday celebrations at Buckingham Palace, or more specifically, a garden party hosted by the Queen.

It's thought that Meghan and Harry, or the Duke and Duchess of Sussex to give them their official titles, have delayed their honeymoon in order to go to today's event.

The bash was attended by many of the people who work with the charities supported by the Prince and representatives from various military regiments. Charles officially turns 70 on November 14, 2018, but the celebrations are kicking off early with a number of events planned throughout the year. It is expected he will have a private party with family and friends on the day itself but this is an earlier public celebration of the milestone birthday, a tradition often followed by the royals.
