The Big Bang Theory actor, Simon Helberg has bought Charlie Sheen’s former Los Feliz home for $2.9 million from Sheen’s ex-wife.  Simon, known for his role as ultra-nerd aerospace engineer Howard Wolowitz on the CBS comedy, has upgraded his living accommodations in a big way with the purchase of Hollywood bad boy Charlie Sheen’s Mediterranean mini-mansion.

The 30-year actor is reportedly shelling out $2.9 million for the Los Angeles, California property.

Sheen purchased the estate with former wife Brooke Mueller in 2007 for $2.575 million and has had the house on the market since mid-2009. Built in 1927, the newly-minted Helberg manor measures in at just under 4,200-square-feet and features a restored interior with Bouquet Canyon stone flooring, capacious living room with trestle-style vaulted ceilings, formal dining room and a generous master suite.
