Australian actress Nicole Kidman and New Zealand-Australian musician Keith Urban.

While singer Keith Urban had wife Nicole Kidman "at his side" as he checked into a rehabilitation treatment centre, the Oscar winning actress' family is standing by her in her time of need.

The country star, who married Kidman, 39, in June, has suffered a relapse in his battle with booze.

And according to The Mirror, the Moulin Rouge star is getting the much required strength from her dear old dad, who co-incidentally also happens to be a top psychologist.

Sources say that Nicole has been having long-distant chats with Dr Anthony Kidman ever since her husband Keith Urban checked into a Nashville rehab centre on Friday.

"Nicole's dad is getting her through it with a mix of professional advice, fatherly guidance and Catholic beliefs. Dr Anthony and his wife Janelle are expected to fly to the USA this week to be by their daughter's side," said a source.(ANI)
