La Toya Jackson is about to walk down the aisle for the second time!

The 58-year-old singer was stunned when her business partner, Jeffré Phillips, 46, popped the question while they were on vacation in Hawaii last August.

“[I was caught off guard so] it wasn’t a fast yes, La Toya admits. “I had no clue. I couldn’t understand why he was so nervous.”

Jeffré had La Toya follow a path of white rose petals and gardenias to their hotel balcony where he had arranged a romantic dinner of her favorite foods, before surprising her with a 17.5 carat diamond ring, which had been hidden under a dessert tray.

“My heart just stopped,” she tells People magazine. “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.”

Though La Toya — the older sister of late “Thriller” hitmaker Michael Jackson — refused to discuss her wedding plans, she hinted fans will find out when she plans to tie the knot by watching her new reality show, Life with La Toya, which airs on OWN beginning June 7.

She teased, “You have to wait to see the show.”
