George Clooney's father NICK has warned the OCEANS' ELEVEN star not to rush into another relationship while he is so involved in his career - because it will lead to more heartbreak.

The father's actor is convinced his son is both marriage and parent material, but insists he must fulfil all his ambitions before a relationship could ever work.

He says, "Some great woman is going to knock him off his feet. He will be a wonderful husband and father. Though I hope he waits until he is at a point in his career where he can devote himself to a relationship.

"George wants to have children but he won't have one without being married, so that is one thing that will force the issue."

Clooney has dated a string of beauties in the past, including Mariella Frostrup, LUCY LUI, Charlize Theron and most recently LISA SNOWDON.
