Rachel McAdams Is the Queen of Romantic Comedies -- See Her Best Moments

As the actress celebrates her birthday, see all the ways that she has made us laugh and cry

When we think of our favorite love scenes or hysterical romantic-comedy moments, most of our picks are films that feature Rachel McAdams.

We cried our hearts out during The Notebook as Allie (McAdams) and Noah (Ryan Gosling) were torn apart by their social classes, and we laughed out loud as John (Owen Wilson) tried to convince Claire (McAdams) to be with him despite his mischievous past in Wedding Crashers.

Now the actress is back with her latest flick, About Time, and we can't wait to add this one to our list! Watch clips of her best rom-com moments (so far!).

In the clip, see what happens when Mary's parents unexpectedly come for a visit.

As the summer comes to an end, so does their relationship when Allie's upper-class status forces her parents to forbid the young couple from seeing each other. Noah writes Allie 365 letters, but all go unanswered. Seven years later, an engaged Allie learns that Noah bought and restored an old mansion that they used to dream of living in. She visits him, giving us the unforgettable rain scene.

If we lost our memory and someone told us Channing Tatum was our husband, we wouldn't question it! When Paige (McAdams) suffers memory loss from a car crash, she remembers her estranged family and past boyfriend, but not her husband Leo (Tatum). As Leo tries everything to help Paige remember their relationship, she finds comfort in her past, especially with her ex-boyfriend. In Leo and Paige's wedding scene, we get a glimpse of how in love they really were before the accident. Can love conquer all -- even a head injury?

In girl world, you never go after your friend's ex-boyfriend, especially if he's the Queen of the Plastics' ex. When Regina (McAdams) agrees to tell Aaron (Jonathan Bennett) that Cady (Lindsay Lohan) has a crush on him, she instead makes him take her back, forcing Cady to seek revenge and take down the Plastics once and for all.

Relationships are hard. Throw in a husband who time travels into the mix, and you have a recipe for heartache. Henry (Eric Bana) is a time traveler who has known Claire (McAdams) all of her life. He can't control when or where he travels to, but big events pull him in. According to Claire, "I was a big event." The two eventually get married and have a child, but Henry's constant traveling leaves Claire alone most of the time. In the final scene of the film, Claire sees Henry for the first time in four years. Get out the tissues!

'Wedding Crashers'
