Rosie, 26, has been vacationing alone with friends this summer, sharing fun pictures of her trip to Ibiza sans her 45-year-old boyfriend.
While Jason was spotted partying with a group of young women in a Manhattan restaurant in June, a source said cheating didn’t play a factor in their breakup.
“There is no other person involved. They love each other very much and are not making an announcement because they’re still hoping to working things out,” the Mail Online reported.
“But things have not been good, there have been lots of arguments and they both need some space.”
As RadarOnline.com previously reported, Rosie warned Jason that he would lose her if he continued his partying ways.
Rosie and Jason have been dating since 2010 and she has gushed in interviews about their relationship, saying: “I’m not interested in hanging out with boys, I have all the man I need. His knowledge
and strength are really inspiring and attractive, and that can come with a man who’s had a bit of time.”
Similar to Rachel and Ross’ breakup on Friends, the source said Rosie and Jason are on a break.
“They are taking some time out from each other. Bear in mind there’s an almost 20 year age gap between them – they are going to run into some issues.”
