"Don't do sex with people without protection #positivetalk #WAD2012," Deena postedon World AIDS Day — a day observed on December 1 every year, to raise AIDS awareness.
And Deena's not the only Seaside roomie who helped raise awareness on Twitter.
Ronnietweeted, "No matter how hard you go at the club remember…. Don’t you ever ever ever ever smush without a condom. #YouFeelMe #positivetalk#WAD2012" and his fellow guido Vinny tweeted, "Getting it in? Wear a condom. #positivetalk #WAD2012."
We're proud of these smush-loving stars for sending the right message!
