Katie Price claims she is bisexual.The former glamour model - who was previously married to cage fighter Alex Reid and singer Peter Andre - made an appearance at Madame Jojo club's 'Trannyshack' night in Soho, London, and told the crowd she is attracted to both men and women. After singing Whitney Houston's 'I Have Nothing', Katie - who has children Harvey, 10, Junior, seven, and five-year-old Princess - announced: ''Do you know what, everyone in here tonight is like me. We're bisexual, I f**k girls. Whatever. I am straight, but I play with the old banjo.'' The 34-year-old star also branded Alex - who she separated from in January 2011 after 10 months of marriage - a ''tranny'' and made lurid revelations about their sex life. She ended her small stage show with a rendition of Whitney's 'Get Here If You Can' before a drag queen assisted her off stage. Katie's sudden outburst about Alex, 37, comes shortly after his former fiancee Chantelle Houghton - with who he has six-month-old daughter Dolly - claimed she discovered sexual texts on the cage fighter's phone to both men and women arranging to meet during their relationship. Chantelle, 29, tweeted last month: ''I didn't know Alex cross dressed cos he told me it was a publicity stunt, I found out when I was pregnant. ''not forgetting the hookers he was texting that he'd had orgies with. Forgive me if I look like s**t right now but I f*****g feel it. ''And I've texted the guy who he was arranging to meet and told him what I think of him too. F*****g sick dragging me into this. It's wrong (sic)''
