Rebound romance for A-Listers?

LONGTIME pal Russell Crowe has been a rock for Nicole Kidman as she picks up the pieces after her devastating split from Keith Urban, say sources who dish sparks are flying between the old friends.

“Russell has been through his own heartbreaking divorce after 15 years of marriage so he can empathize with Nicole in a way that not everyone in her world can,” notes an insider. “He's been on the phone to her nearly every day just to check in and lift her spirits. They even managed to meet up for coffee not that long ago. Nicole is putting on a brave face but she's been rocked by this. Russell has helped to steady her and she's so grateful.”
