As the not guilty verdicts were read out, Mr Frampton broke down in tears in dock, while members of the public gallery audibly sobbed.
The jury, made up of eight men and four women, reached its majority not guilty verdicts after more than 10 hours of deliberation.
The trial heard that a group of women who Mr Frampton had met before his show on the Cowley Road in Oxford had invited the rapper and his friends to a party at one of their houses.
The prosecution had alleged Mr Blake-Walker had raped the one woman whilst being encouraged by Mr Frampton – who, it was alleged, then twice raped the second complainant.
Mr Frampton agreed that sexual activity had taken place between him and the second complainant, but insisted it had been consensual.
Giving evidence during the trial, he said: “I know she was consenting, there wasn’t a question.”
