London, May 1 (Inditop) Hollywood actor Tom Cruise has invited wife Katie Holmes’ widowed sister to move into their Beverly Hills mansion as she grieves the loss of her estranged husband.

Joseph Jeffrey Fretti, who was married to Katie’s eldest sister Tamera, died after suffering a heart attack at his mother’s home in Sarasota, Florida April 12, reported contactmusic.com.

After seeing how worried Katie was for her sister, a single mother of two, Cruise decided to extend a helping hand to his sister-in-law and welcome her and her kids into his home.

“Katie was so worried and upset for Tammy. They are really close and Katie wanted to help any way she could,” said a source.

“Then Tom (Cruise) came up with the idea of inviting Tammy and the boys to live with them. It meant Katie could keep a close watch on her sister and help her through this tough time,” added the source.
