Prince Harry
Prince Harry and Prince William were ushers at close friend Guy Pelly's Memphis wedding.

Prince Harry's reported split with girlfriend Cressida Bonas didn't seem to have dampened his mood too much, as he and his brother the Duke of Cambridge, attended the wedding of his close friend Guy Pelly in Memphis.

‎Harry's former girlfriend, who is also a friend of the groom, was originally expected to attend the wedding, but the couple split after it is thought they had arguments about the trip.

Despite his recent heartbreak, the newly single prince was reportedly seen twerking on the dance floor and happily mingling with guests after the ceremony.

The two princes watched as Pelly and Elizabeth 'Lizzy' Wilson, the granddaughter of the Holiday Inn hotel empire founder, said their vows in an outdoor ceremony in Memphis, Tennessee, under an arch of white sweet peas and roses.

Wearing an elegant white lace dress, the bride made her entrance in a powder blue Thunderbird vintage car.

A cellist performed at the ceremony, which also had choirboys who sang Jerusalem, and a solo female singer who gave a rendition of Amazing Grace.

Later, Prince Harry got his groove on as the Jimmy Church Band performed hits by the Supremes, Marvin Gaye and Stevie Wonder, as well as songs by Robin Thicke, Ke$ha and Katy Perry.

The grand wedding cake, had six tiers and was decorated with two peacocks with edible feathers trailing down the sides.

There was also a groom's cake decorated with a fox dressed in hunting clothes in reference to Pelly's love of hunting.

Laura Jackson, who made the cakes, said: "It is a Southern tradition to have a groom's cake so Lizzy wanted Guy to have one."

The son of wealthy Kent landowners Pelly has been a close friend of the princes for many years, and was often regarded as a bad influence on the young royals.

The 32-year-old organised William's stag do and dressed up as the Queen in 2005 for a fancy dress party when Harry was infamously photographed wearing a Nazi uniform.

The wedding rounded off a private three-day visit to Memphis that included a visit to Graceland, as the princes paid homage to the King of rock and roll, Elvis Presley.
