Dax Shepard is pretty much living with Kate Hudson ... and Kate's estranged husband, Black Crowes frontman Chris Robinson, is thrilled about it. A source told the New York Post:

"Chris is thrilled because now he can have [their 3-year-old son] Ryder whenever he wants . . . Kate gets a little more distracted when new men come into her life." Hudson's rep, Brad Cafarelli, told us, "None of what you're speculating here is accurate." (Source)

And here's the happy couple making out like teenagers last week in Canada. Enjoy it while you can Dax because Kate shares half her genes with Goldie Hawn AKA "the enemy of Kurt Russell's penis since about 1990." You've got a good 10-15 years before she needs to be put down.
