Tom Cruise's mother has passed away at age 80

The actor attended her memorial service over the weekend.

Cruise was close with his mother throughout his life, People reported, and she encouraged him to participate in a local theater group when he was a child. She continued to support his acting career into adulthood, and told Rolling Stone magazine in 1986 that she thought it was a "God-given talent."

"To make a long story short, we gave him our blessing," she said. "And the rest is history."

South was 80 years old.
