Steer clear of Kate Hudson ! Pals say the actress is straining her friendships after splitting with Owen Wilson , a romance first reported on this page.

"Since Owen kicked her to the curb, she has turned into a tyrant to everybody in sight," says one reeling confidant.

"And she just backed off on her offer to buy [estranged husband] Chris Robinson a house in Malibu."

According to the source, the former couple are also squabbling over access to their son, Ryder , who turned three yesterday.

"She's filming in Australia ["Fool's Gold," with Matthew McConaughey ] and she told Chris if he wanted to be with Ryder on his birthday, he had to go down there," said the source, adding that the Black Crowes singer was "kind of broke."

Hudson's rep referred us to her lawyer, who said, "Your source is not credible, as the reported allegations are all untrue ... all matters involving Ms. Hudson's and Chris Robinson's separation and custody matters are private matters upon which we will not comment other than to report that they have all been mutually and amicably agreed upon."

Added the source: "They're ironing out their divorce right now, and there will be a line in it about Chris having 'suitable housing' for when Ryder comes to stay, but she's not going to buy him the Malibu dream house anymore."

No word on whether he gets to keep the pink Barbie Corvette.
