Carey Mulligan is reportedly planning to get married this weekend.

The actress got engaged to Marcus Mumford, frontman of folk group Mumford & Sons, in August last year. Although the pair have kept their romance out of the public eye, it is believed they will tie the knot in an intimate ceremony in the English countryside.

"It's going to be an amazing weekend as they will be surrounded by their closest family and friends," a source told RadarOnline. "It's a dream come true for Carey."

The couple first met in Nashville, where Mumford & Sons were performing last year. Carey had only recently split from Hollywood star Shia LaBeouf.

They may not have been together for long, but Carey is convinced she has found her Mr. Right and she can't wait to get married.

"Carey and Marcus are counting down the days till they tie the knot! She is absolutely walking on air and can hardly contain her excitement," the source added. "They don't care that some of their friends think they are rushing things.

"They are madly in love and know they are perfect for each other."

It was previously reported the pair are eager to set up their marital home in a farmhouse in the southwest of England.

Carey has made no secret of her desire to stay out of the limelight. The Oscar-nominated star recently admitted she would happily give up her Hollywood career and become a housewife if she ever feels disillusioned with Hollywood.

"I'm not going to work for the sake of working," she said in an interview. "I'll work, if I'm extraordinarily lucky enough to continue having the same opportunities, but it will be based on whatever is there. If there's nothing around, then I'll go home and make carrot cake for a while."

Carey, 26, can next be seen in The Great Gatsby, alongside Leonardo DiCaprio.
