Ciara has apologized to her Twitter.com followers after her blog was taken over by pranksters. The singer’s fans were shocked when the 24-year-old star appeared to declare her love for her ex-boyfriend, rapper Bow Wow, by posting a photo of the former couple on her page and writing, “Gosh guys you don’t know how good it feels to be back with Bow again.” But the “Goodies” hitmaker quickly spotted the Tweet and removed it from her page – and now she’s apologized for any offense caused by the bogus post.
