Talk about a stinky situation!
Jennifer is completely blue in body paint as Mystique in "X-Men: Apocalypse," and Nicholas wasn't a fan of how she had to remove it with shaving cream.
"It is really good for taking paint off, but Nick used to hate it because I would come home smelling like a man and, like, too tired," the 25-year-old said. "I was like, 'Don't touch me, I'm too tired,' and he was like, 'You smell like a dude.'"
Jennifer and Nicholas met on the set of 2011's "X-Men: First Class" and continued to work together in "X-Men: Days of Future Past" as well as the upcoming film, "X-Men: Apocalypse," which hits theaters on May 27, 2016.
The co-stars began dating in 2011 but ultimately ended their relationship in August 2014.
In November 2015, Jennifer opened up to Diane Sawyer about how difficult it was to break up with Nicholas.
"These movies had been my life for so long and they had to come first in everything," Jennifer said. "I was also in a relationship with somebody for five years and that was my life. So my life was this person and these movies and we broke up around the same time that I wrapped those movies. Being 24 was this whole year of, 'Who am I without these movies? Who am I without this man?'"
After they broke up, she dated Coldplay's Chris Martin, but she's now single and not worried about it.
"I'm not even looking," she said on Monday. "I'm good."
As for Nicholas, there were rumors earlier this year that he's dating Kristen Stewart.
