Hollywood couple Brad Pitt and Angelina Jolie were spotted shopping in a London sex shop while they were in the UK for the premiere of Angelina’s new animated film ‘Beowulf’ last week.According to reports, 32-year-old Jolie and Brad, 43, enjoyed some retail therapy after posing on the red carpet - at the plush Coco De Mer in London’s Covent Garden, an erotic emporium that stocks 14 Carat Gold Vibrators priced at £249.00 ($498) each and Diamante Nipple Covers at £85.00 ($170) a pair.An onlooker told Britain’s Daily Star newspaper: ‘Brad and Angelina ordered a car to take them directly to the sex store and they browsed the products for half and hour before leaving with a bag of goodies, they also went to look at Ann Summers in Soho.’Meanwhile, Mentewab Dawit Lebiso, the biological mother of Brad and Angelina’s adopted daughter Zahara, has insisted that she is happy for the couple to raise the child, after previous reports suggested she wanted her back in Ethiopia.Lebiso denied making the comments, saying her words were misinterpreted by “so-called journalists” who claimed to be working for Angelina Jolie.She said: “I have never disputed the adoption. It was something I never said.“I think my daughter is a very fortunate human being to be adopted by a world-famous lady. I wish them all the success they both deserve.”
