Reese Witherspoon's children "will love" having a new sibling, according to reports.

The Oscar winning actress is said to be pregnant with her third child, her first with husband Jim Toth.

And Us Weekly claims that her two children with ex-husband Ryan Phillippe; Ava, 12, and Deacon, eight, could not be more thrilled.

"[Her children] will love having a baby brother or sister," a source told the publication.

But the insider added that Jim was a bit hesitant at first about becoming a father.

"Before Jim met Reese, he wasn't sure about having kids," the source said of the Hollywood agent.

"Being around her kids has really shown him what it's all about."

Jim is now said to be "super-close with the kids" and goes to all of Ava's school swim meets and Deacon's basketball games.

"She wants to have this child and take time off," the insider added saying that she was currently craving Taco Bell food.

But Ryan is definitely still an active part in his children's lives and is regularly seen out with them.

"He wants to be around just as often now that Ava and Deacon have a family unit with Jim," another source said. "They mean a great deal to him."
