Charlie Sheen made quite a splash when the drug- and booze-fueled antics in his Mediterranean-style Hollywood mansion came to light. As a result, the new owner of the home – “Big Bang Theory” actor Simon Helberg – will likely be a much more popular tenant in the historic Los Feliz neighborhood. Helberg acquired the mini-mansion, built in 1927, for $2.9 million and now has 4,200 square feet of luxury to explore. The Los Feliz home has been on the real estate market since 2009, just two years less than Helberg has starred on the hit TV series.
