Has your daughter ever kissed a girl? Are you sure? You'd better read this.

Companies are cashing in -- big time -- on this sapphic trend. In fact, Integrity Toys has even created a 12-inch tall Katy Perry doll. The 24 year-old singing sensation's songs "I Kissed a Girl" and "You're So Gay" struck a chord in teenagers, and now they can celebrate her songs -- and her sexual habits -- with the doll created in her likeness.

This craze appears to be here to stay. On today's "Tyra," Tyra Banks explores the issue of so-called "straight" girls who like to kiss other girls. On a typical night out, these girls hit the club scene to hook up with other, well, girls. So why are teens today sticking to their own sex? According to the results of a Tyrashow.com poll about sex, drugs, and violence, 25% of girls ages 13 to 17 admit they smooch their friends to get attention from boys.

Tell us --- would you let your daughter buy this doll? And would you care if she kissed another girl?
