Hollywood heart-throb Tom Cruise, 53, may be about to marry for the fourth time after it was revealed he is head over heels in love with his young British personal assistant.

Emily Thomas, 22, has been working as the star's personal assistant since last year. They met when Thomas was appointed Cruise's on-set assistant for the latest instalment of the Mission Impossible series, Rogue Nation, which is released next week.

The pair are understood to have been romantically involved since last year. They are already thought to be planning a life of matrimonial bliss with rumours that Cruise may even have popped the question during a recent trip to Morocco.

Cruise was in the north African nation scouting for locations for a forthcoming film.

It has even been suggested that Ms Thomas bears more than a passing resemblance to Tom Cruise's third wife, Katie Holmes.

Cruise's spokesman declined to comment on speculation about the star's personal life.

A source said: "Tom has fallen head over heels for Emily, and she feels the same way.

"He always seemed really happy when she was around and incredibly proud to have her by his side."

Tom Cruise divorced Mimi Rogers, 59, in 1990 after three years of marriage.

Later that year he tied the knot with Nicole Kidman, 48, who he divorced in 2001.

Cruise split with actress Katie Holmes, 36, after six years together, in 2012.
