Whitney Houston was out in Los Angeles Thursday night (Feb. 9) to perform at Kelly Price & Friends Unplugged: For The Love of R&B Grammy Party, however, the lauded and troubled singer apparently didn't leave in the best of spirits.

According to The Insider, the 'I Wanna Dance With Somebody' creator threw back a few too many libations at venue Tru Hollywood. She appeared to have a "dazed demeanor" and "aggressive attitude" upon leaving the location. Photos snapped of the six-time Grammy winner -- which can be viewed here -- show her shouting and pointing fingers at the paparazzi.

Before she left Price's event, she joined the 'Not My Daddy' performer -- the song is nominated for Best R&B Performance at the 54th Annual Grammy Awards Sun., Feb. 12 -- to sing 'Jesus Loves Me.' Houston was full of smiles and took the microphone from Price to belt out the song's lyrics.

Several other photos taken upon Houston's exit from the nightclub show blood dripping down her left leg.
