Grant Show is off the market.
The hunky former Melrose Place
actor, 50, is engaged to actress Katherine LaNasa, her spokesperson confirms to PEOPLE.
"Katherine is very excited and already working on plans for the wedding that will happen later this year," her rep says of the blonde beauty, 45.
This will be the second marriage for Show, whose ex-wife Pollyanna McIntosh filed for divorce
in 2011 after they wed in 2004. LaNasa was formerly married to actor French Stewart and to the late Dennis Hopper
Show and LaNasa will both be busy in the months ahead. In addition to planning their nuptials, the actor stars in a new horror film, The Possession
, which comes out at the end of August, and the actress will star in the upcoming NBC series Infamous
, which is set to premiere as a mid-season replacement during the 2012–2013 television season.
