Jade Jagger finds it difficult living in houses.The 36-year-old jewellery designer - who is the daughter of rocker Mick Jagger and his first wife Bianca - lived on the bohemian Spanish island of Ibiza for nine years and found it difficult coming to terms with a lack of space when she returned to London in 2005. Jade - who lives in the exclusive Queens Park area and has a studio round the corner - said: "I love my studio because it is nice and bright, but I find it harder to live in the house because I'm so used to being outside."Jade - who has two children, 15-year-old Assisi and Amba, 12, with ex-partner Piers Jackson - also revealed her "brain stops functioning" when she is in a cold climate.She said: "I'll always have one foot on the beat. It's just the warm weather. I think it must be my South American blood. I really don't like being cold, I get to the point when my brain doesn't seem to function properly."The leggy blonde - who is now dating DJ Dan Williams - is launching a new collection of eponymous titled jewellery Jade Jagger Jewels, which features pieces ranging from £50 to £2,000.
