London, Nov 25 - Rihanna says she is unfazed by talks that she is a bisexual -- a rumour that surfaced after saucy online pictures of the pop star with a woman friend.

Her wild pictures with women have been floating on the Internet since January this year. One picture showed Rihanna fondling the breasts of a female friend, but the 21-year-old has laughed off the snap, insisting that she just appreciates the female form, reports contactmusic.com.
