Is Justin Timberlake calling out his ex, Britney Spears' addiction problems in his concerts? At a recent performance in Zurich, Switzerland, JT started singing Amy Winehouse's hit song, "Rehab." However, he changed the first-person lyrics to "They tried to make her go to rehab and she said no no no." Later on, he sang the Gnarls Barkley tune "Crazy," again changing the lyrics to say, "I think she's crazy... I remember when, I remember when she lost her mind." That's not nice, Justin. Didn't you already get your point across with the Britney look-alike in the "Cry Me a River" video?
