Ryan Phillippe hasn't exactly offered a warm welcome to ex Reese Witherspoon's off-again, on-again guy, Jake Gyllenhaal, according to Us mag. "Ryan is pissed about Jake," a Phillippe insider says, adding that Phillippe told Witherspoon, "he didn't want 'that guy' around their kids and then made some crude Brokeback Mountain remark." However, a Gyllenhaal source told the mag that "Reese doesn't have Jake spend the night when the kids are around." Phillippe is rumored to be dating Aussie actress Abbie Cornish again. "They have been hanging out since June," says a source. The pair were spotted in LA's Franklin Canyon Park on August 5.source
