Reese Witherspoon's new romance wins over ex Ryan Phillippe

Reese Witherspoon's romance with Oliver Haarmann i said to be going strong

Now, insiders claim that the duo's relationship has full support from Reese's ex-husband Ryan Phillippe.

Reese and Ryan share daughter Ava and son Deacon together. They have reportedly reached a positive co-parenting dynamic over the years.

A source told Radar Online, "Now that Ryan is 51 and his kids with Reese are young adults, he shows absolutely no trace of the bad-boy persona that made him famous as a young actor."

"He's a mature, humble, solid guy with an amazing sense of humor. Even Reese can't say enough about what an awesome dad he turned out to be," an insider added. "For his part, Ryan is cheering on Reese's relationship with Oliver, who's integrated himself into her family."

The report also claims Ryan Phillippe has welcomed Oliver Haarmann into the family and sees him as a positive influence in Reese Witherspoon's life. Unlike her previous marriage to talent agent Jim Toth, which sources claim initially made Ryan cautious because of Hollywood power dynamics and younger children at home. Meanwhile, Oliver is reportedly viewed differently.

The source said, "Ryan was a lot more suspicious of Jim at first because the kids were so much younger and Jim was a big-time power broker in Hollywood at the time."

Adding, "But Oliver is a different story. He and Ryan have pretty similar personalities and he's been a great influence on Reese. Oliver has helped her think beyond Hollywood and her business career."

"It's been wonderful for Reese to finally have a relationship with someone who isn't caught up in the L.A. rat race, and Ryan understands that," the insider added.
