The 19-year-old star recently went public with her romance with the 25-year-old model and Paris' brother Prince has reportedly told friends that their late father would be thrilled by the romance.
A source told RadarOnline: ''Prince has said their father would be proud of his daughter for following her own path, as she always has. Michael taught them that love knew no bounds, and that would include race or sexual orientation.''
And friends agree, with the insider explaining that everyone is happy for Paris.
The source added: ''This is indeed a loving healthy relationship between Paris and Cara. It is probably the healthiest and happiest relationship Paris has ever been in, and for that, her family has their full support.''
Although Paris and Cara have been romantically linked for some time, they only went public last week when they were spotted kissing in the street during a double date with Paris' godfather Macaulay Culkin and his girlfriend Brenda Strong.
Cara and Paris reportedly met at the MTV Movie Awards last year and have been spotted on holiday together in London, Italy and the Czech Republic.
Speaking previously about their blossoming relationship, a source told The Sun: ''They really hit it off at the MTV Movie and TV Awards in LA in May and have been hanging out since.
''Cara loves the fact Paris is the daughter of one of her musical heroes.
''She invited her to her Christmas Burberry X bash in London, before whisking her away to Venice then Prague the weekend after, where they celebrated Christmas early at the markets.
''They're both really into their music and have been spending nights singing and jamming on the guitar.
''It's early days, and Cara doesn't really have time for a proper relationship due to her non-stop filming commitments with Carnival Row, but there's no denying there's a spark.''
