Paul Walker with his daughter Meadow
Paul Walker's daughter is reportedly "disgusted" that her grandmother is seeking to be her legal guardian.
Cheryl Walker filed court documents earlier this week in a bid to be appointed Meadow's custodian, following the death of 'The Fast and the Furious' star in a car crash in November, claiming the teenager's mother Rebecca Soteros is an alcoholic.
But a source told E! News: "Everyone was taken by surprise. This has been hard on everyone close to them. [Meadow and her mom] didn't know. There have been discussions but no one told them they were going ahead with it. They first heard about it when they saw it on TMZ. They are very disgusted by this. It is such disregard for their feelings."
The insider predicted that Rebecca wouldn't give up Meadow, 15, without a fight, adding: "She loves her. She has always been and will always be a good mother and there is no reason for a change. She will fight this, I'm sure, until her last breath to be [Meadow's] mom. All she wants is to have her child."
Meadow began living with her famous father full-time in California three years before his death, after moving there from Hawaii, where her mother - who was arrested in 2003 and 2013 for drink driving - raised her.
The source also dismissed Cheryl's claims that Rebecca has a drinking problem, saying: "It's just crazy how people blow things out of proportion.
"Rebecca is a great mother and Meadow is a very happy child. Their relationship is excellent. Rebecca is a former school teacher and good with children."
Meadow is set to inherit Paul's entire $25 million fortune.
The late star appointed his father Paul Walker Sr. as the executor of his will, and stated that Cheryl should become Meadow's legal guardian.
A hearing on Cheryl's request is scheduled for April 30.
