Bobby Brown has reportedly impregnated his girlfriend KARRINE STEFFANS after telling her he'd had a vasectomy. The R+B bad boy moved in with the video vixen-turned-author after his wife Whitney Houston filed for divorce earlier this year (06) and now he's about to become a dad again. According to a report in US tabloid National Enquirer, Steffans, 28, is expecting Brown's fifth child. A source tells the publication, "When Karrine found out she was pregnant she was so angry because Bobby had told her he couldn't have more kids." Steffans and Brown are reportedly making plans for a reality TV show focusing on their romance.
