Robbie Williams has told old pal Nicole Kidman to stick by her man Keith Urban, who`s in rehab with drink and drug issues.
Rob, who`s stayed friends with Nicole since they made Somethin` Stupid together, emailed the Oscar winner urging her to be a `rock` to her country crooner hubby.
Robbie told Nicole, “Please stick by Keith. He needs you now more than ever.”
The singer, who`s conquered his own drug demons, went on, “If he needs anyone to speak to about what he`s going through, I`m here. I know what it`s like.”
Former crack addict Keith – who checked into rehab in the US shortly after he got married – flew to Australia to be with his wife just days ago.
But he`ll be back in the States completing his treatment in the New Year. He`s also had stints in The Priory and Clouds in Wiltshire, reports the Mirror.
