Britney Spears has sparked rumours she's planning to wed for a third time after she was spotted wearing a large diamond ring on her left hand as she left a Los Angeles restaurant with boyfriend ADNAN GHALIB on Tuesday night (15Jan08). The troubled pop star, who lost visitation rights to her two young sons on Monday (14Jan08), was spotted wearing a dress she wore during her 2004 wedding to Kevin Federline over the weekend (11-13Jan08). Insiders claim Spears and British paparazzo Ghalib have discussed a quick wedding, but he's reportedly not divorced from his wife. Ghalib and Spears have been inseparable since the singer hunted him down after a wild night out in December (07). The Toxic hitmaker took her beau to Mexico for a brief break and recently bought him a Mercedes, according to U.S. reports. The singer's companion/manager Sam Lutfi has refused to comment on any marriage plans, but he insists tabloid reports suggesting Spears is pregnant are "100 per cent not true". Spears and Ghalib were spotted looking at pregnancy tests at a Los Angeles drug store on Monday night (14Jan08).
