Singer Cassie is furious after pictures of her posing topless leaked onto the Internet. Personal photos of the R&B beauty hit the web on Wednesday and quickly spread to a number of gossip blogs.

And now the star, who most recently made headlines after shaving her head, has taken to her page on social networking website Twitter.com to accuse the person responsible of hacking into her computer and stealing the saucy snaps.

She writes, "It seems that someone has hacked into my computer...that's real foul and evil... Now stop acting like you haven't seen a t--ty before."
