The 28-year-old 'Anna Karenina' actress married Klaxons musician Righton in France last weekend and after the ceremony, the keyboardist presented her with the 3,000 pounds tree which also has their wedding date carved on it, reported Sun online.
"James had it planted in the back garden of her home in France on the day of the wedding. He had carved their initials in a heart and showed her in front of everyone. She collapsed into fits of giggles, it was very sweet," a source said.
And Keira's wedding band used to belong to James' grandmother. "The ring he gave her was a family heirloom too. He really did think it all through. It was an amazing wedding, the whole thing was really sweet and down to earth," it added.
The couple married in a small ceremony at the town hall in Mazan, 67 miles from Marseilles, before speeding back to her family's nearby USD 5 million vineyard for a 50-guest reception in a silver Renault Clio.
