Londoon: "The Vow" star Rachel McAdams, who is dating actor Michael Sheen for two years now, is reportedly going to tie the knot with him. Sheen is set to pop the question soon, reported a magazine.

"Michael is planning on proposing to Rachel very soon. They both want to take their relationship to the next level. They are madly in love and want to start a family together," a source said.

 The couple met on the sets of Woody Allen's romantic comedy "Midnight in Paris". McAdams has previously said she has always wanted to get married and have children as she thinks it is one of the most"romantic and strong" gestures a person can make.

"Getting married and having children is something I've always wanted. I think that to make a public vow is a really romantic and strong gesture," she had said.
