Talk about friendly competition. During an interview with MTV, Dear John stars Amanda Seyfried and Channing Tatum get feisty when talking about Miley Cyrus.

"If The Last Song was coming out the same weekend as Dear John, we'd have to collaborate on some sort of sabotage mission," Amanda kids. "I'd burn it," Channing chimes in.

Why the rivalry? Miley, along with her real life boyfriend Liam Hemsworth, star in The Last Song, the other movie coming out this year from The Notebook's author Nicholas Sparks. The flick's release date was recently pushed up so it will now hit theaters on March 31.

"He's got, like, a magic wand when it comes to heartstrings," Channing says about Sparks. "I think he's a hopeless romantic himself and he just really loves writing about it...I think all his films are very, very separate from one another with one theme: love."

In its opening weekend, Dear John beat out Avatar for the No. 1 spot at the box office. The Nicholas Sparks adaptation starring Amanda Seyfried and Channing Tatum took in $32.4 million, while Avatar came in second with $23.6 million.

After eight-weeks in theaters, Avatar has earned a whopping $630.1 million, but these most recent numbers may be a sign that people are over the Na'vi people and ready for romance (Valentine's Day is this weekend after all).

However, Amanda thinks that Dear John is "different" from other romance films, and ultimately, audiences are want to see inspiring movies no matter what they're about.

"I know Avatar is a huge blockbuster and everyone wants to see it and everyone is inspired by that, but that is unique," she says. "I know obviously it's in theaters today, but that is just a really unique film and it brings so much inspiration. I think [Dear John] is the type of movie that normally does [inspire] and isn't out enough."

Amanda and Channing had a lot more to say about the film and their future projects. Read more from our exclusive interview with the Dear John stars here!

Spoiler alert! We don't want to give away the ending of Dear John, but Amanda Seyfried kind of does in our recent interview with the 24-year-old star.

"I'd make it happier," she says about changing the end of the movie. "I was so depressed after I saw the first cut of that film."

Uh oh! Well, we knew that the Nicholas Sparks adaptation would be a tear-jerker, so an emotional ending is a given. But is it too sad?

As for the the roles of Savannah and John, it's no wonder why Amanda and co-star Channing Tatum were cast. The two actors have had plenty of experience with romance films in their careers, but ideally, they'd both like to flip the switch and change things up a little.

"I kind of want to play a villain," Channing admits. "I haven't played a villain yet and I want to go down that dark road and see what happens."

It's hard to believe that anyone ever broke up with Channing Tatum, especially considering how handsome he looked on the red carpet of the Dear John premiere in Los Angeles on Monday. That girl is probably kicking herself now!

Channing posed for pics with his co-star Amanda Seyfried, who rocked this stunning navy and silver block dress for the celeb-filled event. She accessorized with drop earrings, a clutch and platform peep-toes that completed her look perfectly.

Channing's wife, actress Jenna Dewan, also showed up to the screening to support her husband along with Haylie Duff, Max Ehrich and many others. Of course, author Nicholas Sparks, who wrote the book from which the film was adapted, was also there.

Amanda Seyfried and Channing Tatum are gearing up for the release of their epic romance film Dear John, and we got to talk to the two stars all about it!

The movie follows a Savannah and John, who fall in love while John is on leave from the Army and Savannah is on break from school. One of the unforgettable scenes is the heart-melting kiss in the rain we've seen in the latest movie clip. So naturally, we wanted to know if Channing had any real-life experiences like the one in the movie.

"I'm from Florida, and it rains pretty much all the time, so yes, I did for sure," he tells JSYK. "Everyday after school, [at] 2:30, 3 o'clock, it's raining, so absolutely."

As for Amanda's past, she reveals that she had a high school love that has stuck with her for years. "It was with a boy who I was obsessed with, in a way, because I thought he was a cross between Leo Dicaprio and Justin Timberlake, in my eyes, when I was 14," she explains. "He was a senior and I was a freshman and he wanted to date me. He was a friend of my sister and he found some weird sophistication that he thought I had that my friends didn't. So we dated and I totally couldn't deal with the fact that he liked me so much, so I dumped him like three months later."

Dear John opens in theaters in just two weeks, and we can't wait to see what's in store. To psych you up for the romance film adapted from Nicholas Sparks' novel of the same name, we've got a clip from the movie featuring its stars Channing Tatum and Amanda Seyfried.

In this scene, Savannah and John run under the shelter of a construction site to escape from a rainstorm. Savannah asks John about a scar on his face, and he eventually reveals that he's not the same person he was back in the day. "They're not scared of me," John says of the way people in the town look at him. "They might be scared of who I used to be."

Who did he used to be?! What does this mean for Savannah? We have all sorts of questions that will only be answered when the movie comes out on February 5. Check out the new clip from Dear John after the jump.
