The Texan supermodel has defended her 71-year-old ex-husband - with whom she has four children, Lizzie 30, James, 28, Georgia, 21, and 16-year-old Gabriel - for being pictured with other women months after the suicide of his long-term girlfriend L'Wren Scott in March, insisting the criticism of his actions has been unfair.
She told the new issue of Good Housekeeping magazine: ''I didn't see any of that. He is single now and he can do what he likes.
''We are very, very friendly. We speak about the children and we really get on well.''
Jerry admits L'Wren's death has been ''traumatic'' for the whole family, but the Rolling Stones rocker has been getting through the ordeal thanks to a ''lot of love and support'' from his kids'', which also include Karis, 43, and Lucas, 14, from other relationships.
She added: ''It was very traumatic for the whole family.
''We all got on really well, peace was reigning. It was a shock for the whole family, and Mick was just devastated - it was a big shock for him.''
While the 58-year-old beauty is grateful she and the 'Paint it Black' rocker - who she split from in 1999 after nine years of marriage - still get on well, she admits it has been ''challenging'' making family life work because there are so many people involved.
She added: ''Of course it is challenging. Because we used to be married and you have a divorce and then there are children from different mums ... I'm sure anyone would agree that is a challenge!
''But we all love each other, and I get on great with all the mums.''
