Brad Pitt and Angelina JolieBrad Pitt has bought Angelina Jolie an ivory and quartz crystal stone at a jewellery store last weekend, sparking yet more rumours that the pair are intending to marry in the near future.

According to local Namibian custom, grooms present their brides with the gem as a pledge of fidelity.

The pair have been rumoured to be about to marry since they announced Angelina was pregnant last year and sparked a media stampede to Lake Como in northern Italy last month when the couple seemed set to marry at friend George Clooney’s villa.
