Whitney Houston was a pop diva through and through and she didn't have much interaction or crossover with the hard rock world or community, but that doesn't mean that her unexpected death yesterday (Feb. 11) at age 48 didn't resonate with the rock community.

Several rockers posted tweets and Facebook messages about the legendary singer's death.

Poison singer Bret Michaels took to Facebook to eulogize Houston, recalling his meeting with her.

Michaels posted:

"My deepest condolences to Whitney Houston's family and friends. I first met Whitney when we were in Rome on tour. I couldn't sleep so I went down to the lobby. There she was sitting on the couch reading a book, apparently she couldn't sleep either. We sat and hung out chatting for quite a while. She was awesome. Over the years, we ran into each other at several other events, the most memorable being when we were performing in Rio for the Hollywood Rocks festival. I happened to walk up to my room from the pool where a bunch of us had been sitting and saw the news about the Northridge earthquake. I remember telling her, the guys from Aerosmith and others about the news... Again... what a great person with a great voice and amazing talent. She will be missed. My deepest condolences to Whitney Houston's family and friends."

Someone on the official Guns N' Roses Twitter account posted: "Now like then when you see her face, she takes you away to a special place... – RIP Whitney Houston"

Otep wrote: "R.I.P. Whitney Houston, a gargantuan voice but couldn't sing her demons to sleep. It's just so senseless. Much ♥ to her family, friends, & fans. #OTEP."

Sebastian Bach was particularly devastated about the death of Houston, posting: "This is hitting me hard. I used to sing ALL of Whitney Houstons songs all the time. I absolutely loved her voice. I practiced along to her songs countless times & her music affects me deeply. I cannot believe how temporary life is. How fragile music is. Everything you know, everything you hold dear can be ripped away at a moments notice & you won't even see it coming. I always figured Whitney would record another record that would blow us all away. So sad that was not meant to be. 48 years old? Ugh. It makes me sick. Such a loss RIP Whitney Houston My condolences to my friend Bobby Brown & his children."

Nickelback also weighed in, tweeting: "Rest in Peace Whitney Houston. Thank you for the gift you gave us all."

Guns N' Roses and Sixx:A.M. guitarist Dj Ashba tweeted: "RIP Whitney Houston. Bummed! The world lost the voice of an angel today, you will truly be missed."

Stryper vocalist/guitarist Michael Sweet took to Twitter: "Heartbreaking to hear about Whitney Houston. So young and so very talented. Thoughts and prayers for the family."

Slash tweeted a couple of hours after the news broke: "Shattering news about Whitney. RIP."

Janes Addiction's Dave Navarro tweeted: "Very sad to hear about Whitney's passing."

Testament guitarist Alex Skolnick commented about Houston's enormous talent: "Like many R&B artists, some tracks were a bit polished/produced 4 my taste. But man, what a voice!! Had to give it up 2 Whitney."
