London: Kate Moss treated Sadie Frost to a £25,000 friendship ring for her birthday.  The model bought her best friend the expensive gift and the actress’ boyfriend James Gooding is said to be angry at being upstaged by the ‘’lavish’’ present.  Speaking to the Daily Star newspaper, a source revealed: ‘’Kate really pushed the boat out for Sadie’s 48th birthday.  ‘’They’ve been friends 15 years and Kate wanted to spoil her but Sadie’s fella scoffed when he saw the lavish gift.  ‘’He thinks it’s ostentatious and an inappropriate present from one friend to another, especially as it’s not even a milestone birthday.’’–SS
