Bob Geldof's daughter Fifi is engaged. The 31 year old, Geldof's eldest daughter, is set to wed her 33 year old busker beau Andrew Robertson. She took to Instagram.com to post a close-up photo of her left hand, showing off a sparkling diamond ring on her ring finger, along with the caption, "The ring #boydonegood." She follows in the footsteps of her famous father, who is also planning to walk down the aisle with his long-term girlfriend, French actress Jeanne Marine. The happy news is a welcome reprieve for the family, who are mourning the loss of Geldof's 25-year-old daughter Peaches, who died at her home in Kent, England in April (14) after taking heroin.
