Hollywood actor Jim Carrey is reportedly dating make-up artist Cathriona White who hails from Tipperary.

The 50-year-old Dumb and Dumber star is said to be smitten with 26-year-old Cathriona White who he has been dating for the past month.

A source told RadarOnline: "Jim and Cathriona have been dating for over a month now. She comes from a very small rural village in County Tipperary and left Ireland for Los Angeles after studying to be a beautician.

''Cathriona is ambitious and is working as a make-up artist in Hollywood - and she's already worked on many film sets since arriving in the States."

Jim was previously married to waitress Melissa Womer from 1987 to 1995 and to Lauren Holly from 1996 to 1997. He split from long-term girlfriend Jenny McCarthy in 2010.
