Reese Witherspoon and Ryan Phillippe fighting over children?

Reese Witherspoon's ex-husband Ryan Phillippe is reportedly furious that his children are spending "too much" time with Reese's new boyfriend, actor Jake Gyllenhaal.

The pair - who divorced last year, both waited for their divorce to become final before going public with their new romances - with Reese keeping the details of her relationship with the 26-year-old 'Jarhead' actor private until just recently.

According to sources, Phillippe, 33, is upset at how much time his two children, Ava, 8, and Deacon, 3, are spending with Jake. According to a family friend, the kids love Jake so much that when it's time for Reese to hand them over to Ryan, Deacon can't stop talking about Jake. "It's Jake did this, Jake brought mommy flowers and coffee, Jake says we should recycle," the friend tells America's OK! magazine.

And it's reportedly taking its toll on Ryan - who met Witherspoon at her 21st birthday party in 1997, the source added: "Ryan called Reese and suggested she stop letting him [Jake] spend so much time with the kids.

"He was pretty irate on the phone. Reese barely let him finish the sentence before she shot back that what she does with her personal life is her business."
