Jennifer Aniston made sure to slam her "We're the Millers" co-star at the MTV Movie Awards.

On Sunday night, the award for Best Kiss went to Will Poulter, Jennifer Aniston and Emma Roberts for their three-way kiss in the hilarious comedy.

According to MTV.com, Jennifer Aniston didn't want fans to know that she had kissed her much younger co-star voluntarily.

While the British actor was on-stage accepting the award, Aniston sent Poulter a text saying, "I was forced to kiss you."

Young Will reportedly played it off well and even decided to fight back, saying, "You look like a dorky Tintin." For those who don't know, a dorky Tintin is the French comic book hero who is known to be incredibly awkward.

Despite his co-star's comment, Will Poulter had a good night, taking home the award for Best Breakthrough Performance for his role on "We're the Millers."

As Jennifer "jokingly" insults her co-star, she has also been photographed working on her new film, "Cake."

Aniston was recently seen with no make-up on the set of the upcoming film starring Anna Kendrick and Sam Worthington.

We have to say, the actress looks quite radiant as she smiled for the cameras.

Variety reported that the stunning 45-year-old actress would be starring in the Daniel Barnz-directed film back in February.

The movie is reportedly about a woman named Claire Simmons who becomes obsessed with the suicide of another woman in her chronic pain support group.

The "Friends" star is also executive producing the film.

Jennifer Aniston's personal life seems to be going just as well as her career. Us Weekly has reported that Justin Theroux and Aniston have picked Hawaii for their wedding destination.

The rumors of Aniston being pregnant with Justin Theroux's child are false as well as rumors of them ending their relationship.

Justin Theroux and Jennifer's wedding details will be coming shortly.
