Late Sunday afternoon, People Magazine dropped the bomb! Jake Gyllenhaal and Reese Witherspoon are O-V-E-R. And if it’s People Magazine doing the first reporting on it, you know the source is coming straight from Reese or Jake, or both. So, yeah – they’re done. They’ve been dating since maybe late 2006, when they were working on Rendition, after Reese and Ryan Phillippe separated and began divorce proceedings. As far as I know, I think Jake is the only person Reese has dated after her split with Ryan. Jake was also photographed with Reese and Ryan’s two kids often enough, so you know that the relationship was something real – real enough to have Jake acting like a step-dad, at least.

Reese Witherspoon and Jake Gyllenhaal have split, a source close to the actress tells PEOPLE. No further details were given.

Witherspoon, 33, and Gyllenhaal, 28, costarred in the 2007 movie Rendition, after which rumors started flying about them as an off-screen couple.

By the summer of 2008, however, the rumors appeared to be confirmed, thanks, in part, to an extended Bastille Day holiday in Paris – followed, the next month, when they were seen in Marrakech, spending a Saturday strolling hand-in-hand, checking out bazaar stalls, before stepping into the shade for lunch, according to reports.

Come that Sunday, the couple reportedly stayed in their suites at the 5-star Amanjena Hotel, described as a beautiful, romantic getaway boasting a view of the Atlas Mountains.

By that fall, Witherspoon was telling Vogue about Gyllenhall: “He’s very supportive. Suffice it to say, I’m very happy in life, and I’m very lucky to have a lot of really supportive people around me who care very much for me, and, you know, that’s all you can hope for in life. I am very blessed in that way.”

This spring, in April, the two enjoyed a steamy escape to the Southern California desert, where they looked cozy together at the Coachella Valley Music & Arts Festival. “Reese looked cute in a hat and bikini,” an eyewitness told PEOPLE. “She was in a great mood and kept chatting with Jake between sips of a piña colada.”

And as recently as last month, things still appeared to be running smoothly between the two, with Witherspoon telling InStyle, “We spend the weekends outside L.A, in Ojai, where I have a farmhouse. We have chickens and we grow cucumbers and tomatoes. I love it. It reminds me of where I grew up in Tennessee.”

I asked CB if she thought Jake was gay, since I know that’s coming – you know, a lot of people will be like “oh, it was a fake relationship anyway, Reese was a beard.” But I don’t think Jake is gay, and CB doesn’t either. Granted, he twitches a little on the gaydar, but CB thinks he’s just one of those ultra-sensitive metrosexual-types. She also thinks that he’s probably got commitment issues, and that they’ve been broken up for at least several weeks, judging from all of the photos of Reese solo, looking grumpy. To me, Jake seems like the kind of guy who is compulsively wholesome – utterly vanilla, always interested in being “the good guy” and the savior. I’d imagine he’s one of those men who likes to “fix” damaged women. As for Reese – well, I like her, but I get that she’s not everybody’s cup of tea. She seems really anal-retentive and high-maintenance, which would be a turn-off for a lot of men. Jake managed well enough for years though – so I really have no idea what broke them up. I suspect we never will know – Jake and Reese don’t seem like the kind of celebrity to use a split to win sympathy points.

UPDATE: Now People Magazine has a denial from their reps Nanci Ryder and Carrie Byalick, who rep Witherspoon and Gyllenhaal respectively- they told People, “It’s not true…They are still together.” Whatever. I guess maybe they’re hanging on.
