Britney Spears thinks there's something not quite right about how Brittany Murphy died a sudden death, and she has good reason to wonder ... because there's a direct connection between them.
The singer just posted about the late actress, saying she finds it "curious" Brittany died at just 32, and doesn't seem to buy the official explanation. Britney admits she's a bit late to the discussion -- she references a People cover story from last October.
As you know ... Brittany was found unresponsive back in 2009 in her Hollywood Hills home, and the coroner ultimately determined she died of drug intoxication and untreated pneumonia.
What's interesting is the fact Murphy bought that house from Spears, who lived there back when she was dating Justin Timberlake.
