Jennifer Lopez is selling off all the jewellery Marc Anthony gave her during their seven year marriage. The singer is even said to want to get rid of her stunning $4m engagement ring in a bid to make a fresh start. Her most prized jewel is the rare blue 8.5 carat diamond in her engagement ring. Lopez, 42, is also giving away clothing that was bought by Anthony during their romance and marriage. Lopez is said to only be keeping items that were given to their three-year-old twins Max and Emme. The sale of jewellery comes after reports Anthony has banned his ex-wife's new boyfriend from driving the children around because of his driving record. .
