Ronnie Wood's ex-wife is glad the rocker has found love again, but she has warned his new partner will be in trouble if the reformed alcoholic starts drinking again.

The Rolling Stones guitarist married for a third time when he exchanged vows with theatre producer Sally Humphreys in December (12), four years after splitting from his second wife, Jo, in 2008.

Jo has now spoken out about the rocker's latest trip down the aisle, insisting she is pleased he remarried, but hopes he doesn't go back to his previous bad habits.

She tells Britain's Weekend magazine, "I'm happy for Ronnie... He should be proud he's finally stopped drinking and I'm happy he's found somebody else, too. I just hope he doesn't go back to what he was like."

Wood endured numerous trips to rehab over the years as he struggled to ditch booze and is now sober after quitting drinking for good, but Jo reveals he was going through crates of vodka at the height of his troubles.

She adds, "Towards the end of our marriage, his alcoholism reached a grand scale and he used to have crates of vodka delivered to the house... Ronnie's drinking was completely out of control."

Wood was previously married to Krissy Findlay from 1971 to 1978.
