"No split!" the rep told Access.
Similarly, a rep for Reese told Us Weekly that the couple was still together.
Earlier on Sunday, People reported that the couple had called it quits, citing a source close to Reese.
The couple, thought to have linked up on the set of 2007's "Rendition," have been photographed in recent months out hiking in Los Angeles and enjoying the performances at the Coachella Music Festival earlier this year. The couple moved in together last year, according to several reports.
"He's fabulous," Reese said about Jake in the April 2009 issue of ELLE. "He really is a fantastic guy."
Jake appeared happy and animated to Access Hollywood producers at the press junket for his latest film, "Brothers," at the Four Seasons Hotel in New York last Saturday, joking with members of the press and showing no signs that any split was imminent.
