Jerry Hall has been flying back and forth between America and Britain to visit her sick mother in hospital.
The Texan model, who lives in the U.K. with her children, has been returning to her home state regularly after her 87-year-old mum Marjorie suffered a heart attack.
Sir Mick Jagger's ex-wife, 55, tells Britain's Daily Mail, "I have been travelling to and from the States to see my mum. She's been very unwell with heart problems and I have been visiting her in hospital. We are close so it's very sad."
