South died peacefully in her sleep last week (ends10Feb17) and was remembered at a memorial service at her local Church of Scientology over the weekend (11-12Feb17), according to People magazine.

Cruise, 54, and his sisters, Lee Ann DeVette, Cass Mapother, and Marian Henry, were in attendance.

The movie star and his mum, a retired teacher, had a close relationship, and she often joined him on the red carpet at film premieres.

Tom even credited his love for acting to his mum, telling Rolling Stone magazine in 1996, "I was always interested in theatre, but I never did anything with it. When I was growing up, if you went to Hollywood, that was really risque."

South encouraged her son to audition for his school's production of Guys and Dolls after Cruise injured his knee, putting his wrestling days on hold.
