Will Arnett may have found a new love in celebrity chef Katie Lee, but not everyone involved is loving the new situation they’ve found themselves in.

Will, who separated from wife Amy Poehler in 2012 after nine years of marriage, is trying to make his new relationship work as a single dad, although the two women in his life are at odds over just how that should play out.

RadarOnline reports that Katie is having a difficult time dealing with Will’s laissez-faire attitude when it comes to Amy’s parenting.

“Katie Lee’s been telling her friends how happy she is dating Will,” reveals a source close to the couple. “But the way that Amy deals with the co-parenting aspect of their split is really getting on her last nerve. Katie is constantly complaining that Amy is making too many demands on Will about his responsibilities and commitments to take care of the kids.”

Adds the source, “Amy sort of wore the pants and did what she wanted, when she wanted, with whoever she wanted.”

Despite Will’s seeming infatuation with Katie, who has no children of her own, the source says that she’ll definitely have to prove she can play nice with baby mama if she wants her relationship to continue long-term.

“Katie Lee has to realize that if she’s going to make it work with Will, she’s going to have to make it work with Amy and the kids, too.”
