Troubled British singer Amy Winehouse briefly left rehab today to renew her visa with the intentions of appearing at this Sunday's Grammy Awards, Us Magazine reports. Winehouse might attend the awards on Sunday with a chaperone and return to rehab when she arrives back in the U.K. If she does attend, there's still no word on whether or not she will perform (as Mark Ronson hinted to Rock Daily a few weeks ago), but she is likely to win at least one of the six awards (including Album of the Year and Record of the Year) for which she has been nominated.
