Today, November 19, marks Prince Harry and Meghan Markle's six month wedding anniversary.

The royal duo tied the knot on May 19 at St George's Chapel in Windsor Castle and since, have undergone a whirlwind couple of months including an abundance of UK engagements, overseas trips, a 16-day royal tour and lastly, the announcement of their royal baby, due in spring 2019. Yes, it has been nothing short of hectic for the Duke and Duchess of Sussex who today, celebrate six months of marriage. And so, to mark the occasion, having spent the day in private, the pair will head out tonight for the Royal Variety Performance at the London Palladium.

Prince Harry meeting Little Mix at the Royal Variety in 2015.

A first for the duchess, the Royal Variety is a spectacular night full of glitz, glamour and a wreath of talented acts. Headling the bill tonight includes Take That, the cast of Hamilton, George Ezra, Clean Bandit, the cast of The Tina Turner Musical and Andrea and Matteo Bocelli. It is reported that Harry and Meghan will be meeting various performers in the show both ahead and after their performances as well as television executives and members of the Royal Variety Charity.

This will be Meghan's first time at the annual event.

Harry first attended the Royal Variety in 2015 and so, he's well accustomed to the protocol. Last year, Kate and William attended the event when Kate was at the early stages of pregnancy with Prince Louis. Tonight however, it is expected Prince Harry and Meghan Markle will be the only royals in attendance.
