Wiz Khalifa and Kanye West's ex has long been perceived to be openly bisexual, saying a few years ago that she is "extremely open with my sexuality. I can be in love with a woman, I can be in love with a man. Iâm not into bestiality, but as far as humans go, I definitely find beauty in everybody â¦ If I see a women and I think sheâs beautiful and I like her, and she likes me back we can definitely try to be in a relationship together."
Currently married to wife Christine Marinoni, Sex and the City star Cynthia Nixon confirmed in a January 2012 interview that she is bisexual, even though "I donât pull out the 'bisexual' word because nobody likes the bisexuals. Everybody likes to dump on the bisexuals... We get no respect."
The Biggest Loser coach and personal trainer Jillian Michaels said in 2010, âLetâs just say I believe in healthy love. If I fall in love with a woman, thatâs awesome. If I fall in love with a man, thatâs awesome. As long as you fall in loveâ¦ itâs like organic food. I only eat healthy food, and I only want healthy love!â
"I'm among the millions of parents who have been in a gay or lesbian relationship. It hasn't been an easy road, but I feel there are no mistakes in my life. Everything happens for a reason. To have the opportunity to speak for myself and to have people understand what I'm going through is really special. I myself was confused and scared at first. Being able to speak from my heart and get this all out, it's a huge relief for me." - Kim Zolciak
Tila Tequila is not one to shy away from anything, so it's perhaps no surprise that she's bisexual, and has let everyone know it. She even did a reality show featuring both genders called A Shot At Love With Tila Tequila.
