The 30-year-old actress married singer-turned-actor Justin Timberlake in Italy last Friday after dating for five years, reported E! online.
"She said that she's changing her last name legally and Timberlake is the coolest last name she has ever heard," a source said.
The 'Total Recall' actress tied the knot with the 'SexyBack' singer following four days of celebrations at the luxurious Borgo Egnazia resort in Puglia, Southern Italy, and the couple say they could not have asked for a better day.
"It was a total fantasy experience. It was a really special evening," she had said.
