Tom Cruise‘s son, Connor, and Kirstie Alley‘s daughter, Lillie, have reportedly formed a special relationship following the recent death of Lillie’s fiancé.

According to a new report, Connor Cruise, 20, has been comforting Lillie, also 20, after her childhood sweetheart, Nick Trela, was sadly killed in a motorcycle accident in November 2014.
