Singer La Toya Jackson is engaged to marry her business manager.

Michael Jackson's 58-year-old sister accepted Jeffre Phillips' proposal after he popped the question on vacation in Hawaii last August (13).

Jackson took her time while deciding whether to accept Phillips' proposal because his romantic gesture came as a shock, explaining, "It wasn't a fast yes."

She adds to, "I had no clue. I couldn't understand why he was so nervous. I was in total shock. We're best friends and we've been business partners forever. It was always professional - no one really crossed those boundaries."

The news comes six months after reports suggested the pair had secretly wed in Los Angeles in December (13).

Jackson later denied the rumours, calling them "completely false."

The star was married to her manager Jack Gordon for seven years before they divorced in 1997. She alleged he had been abusive throughout the union.
