'Hunger Games' star, Jennifer Lawrence, is believed to have ended her relationship with the Coldplay frontman just four months after they started dating.
A source told People.com: "Jen is the one who broke it off with Chris."
Their split comes just weeks after the 24-year-old actress introduced Chris to her parents.
Jennifer reportedly flew her mother, Karen Lawrence, into Los Angeles to meet the 'A Sky Full Of Stars' hitmaker.
The actress's grandparents confirmed the development in the couple's relationship.
Her grandmother Carolyn Koch said: "Jennifer's mum flew to Los Angeles to meet Chris. We will have to get another chair for the dinner table at Christmas.
"The family is getting so big; we might have to split up for gatherings."
Chris - who split from Gwyneth Paltrow, his wife of 11 years, in March this year - appeared to confirm his new relationship when he was spotted kissing his new girlfriend at a concert in Hollywood.
However, according to her grandfather, Colin Koch, Jennifer is reportedly not so keen on the public attention she receives.
He explained: "Jennifer doesn't like the hype. She looks like she really enjoys doing TV interviews but she's just a great actress."
