Amy Winehouse has infuriated her mother-in-law by celebrating the New Year with an ex-boyfriend. The Back To Black star spent a festive holiday (Dec07/Jan08) on the Caribbean island of Mustique as a guest of singer Bryan Adams. But the star - who agreed to the trip to take her mind off the jailing of her husband Blake Fielder-Civil - spent the duration with former beau George Roberts. And the trip has infuriated her mother-in-law Georgette Fielder-Civil. She says, "What signal is it sending out? Amy's husband is stuck in jail and she's cavorting with an old boyfriend. What's she playing at? It's just not on."
