Just ask those in her inner circle like Madonna, Stella McCartney and Liv Tyler. As hellomagazine.com reported this week another close pal of the actress - Rosario Saxe-Coburg, neé Nadal – is in need of her support amid difficulties in her personal life. In the wake of an announcement that the Spanish beauty has separated from her husband Prince Kyril of Bulgaria, the two friends were spotted enjoying a girls' day out at a London arts fair. Gwyneth, a lover of Spain since she spent a year there as a language student, has plenty in common with Majorca-born Rosario, 40, who is an independent art consultant. Both are muses for Valentino and regulars on the glittering London social scene. Rosario and the 45-year-old prince, a top trader with hedge fund GLG said to be worth £25 million, have not yet announced plans for a divorce. They've been living separately for around four months, however. Kyril has hired a studio flat near the family home to be near the couple's three children - Mafalda, 15, Olimpia, 13, Tassilo, seven - and can help out with the school run to the French Lyceé they attend.
