Jennifer Lawrence hilariously vandalized a bus ad that had her "Passengers" co-star Chris Pratt's face, while on "Jimmy Kimmel Live" on Monday.

Oh, it wasn't just for fun. The actress had been wanting to seek revenge on Pratt after he had posted several pictures of them, but with Lawrence's head intentionally blocked or cut off. Thankfully, Kimmel had given her the perfect opportunity to do it on television!

During the interview, the Hunger Games actress intended to promote their new movie but also ended up talking more about how much of a "hypochondriac" she was. 

To explain just how obsessesed she was about her health, she recalled how she infamously told the host that her "breasts are uneven" during her first visit on his show in 2013. As it turns out, just hours before the broadcast, she went to see the doctor for walking pneumonia and realized the "problem" while getting a chest X-ray for her lungs

She added that she actually likes "going to the doctor" and is an "alarmist." If that is not weird enough, she also noted that her intestines bled one time after allegedly stressing herself too much.

All the health talk led the host to share that he had appendicitis, to which the actress responded that it was her "dream" to have one. They later talk about bacteria (seriously), which Lawrence also had on her phone. Wow.

Going back to her funny revenge on Pratt, check out how Lawrence defaced her co-star below:
