Whitney Houston took the mic and performed “Yes, Jesus Loves Me” at the Kelly Price & Friends pre-Grammy concert on February 10th.

It would be her last performance.

On Thursday afternoon at the hotel, Houston drew the attention of reporters and security staff with her erratic behavior, dripping sweat and disheveled clothes.

The singer was disruptive at that day’s rehearsals for music mogul Clive Davis’ annual party; that party at the Hilton on Saturday night was supposed to include a performance by Houston.

According to TMZ, Whitney “partied heavily” last night at the Beverly Hilton hotel where she was staying, drinking and chatting loudly with friends in the bar.

Houston’s bodyguard found her body, said Courtney Barnes, publicist for hip-hop artist Ray J, who was dating Whitney.
