Sienna Miller: Keira doesn’t need parenting advice

Sienna Miller’s been offering Keira Knightley advice on motherhood.

Miller, who has a 2-year-old with actor Tom Sturridge, told us of pregnant pal Knightley at the premiere of “American Sniper,” “We’ve spoken a lot and I know she will be amazing.”

But it seems that Knightley (who Page Six first reported is expecting with rocker James Righton) already knows what she’s doing.

“She doesn’t need any advice. She will be perfect,” mused Miller, who just posed with daughter Marlowe in Vogue.
