Kelly Rowland feared for her life when she was lost at sea.

The 'X Factor' USA judge was involved in a dramatic rescue mission last month during a botched whale watching trip with four friends on a private rented boat in Provincetown in Cape Cod, Massachusetts.

The 32-year-old singer has now revealed she thought she was going to die when they lost sight of the boat they'd been following and got caught in winds of up to 30 miles per hour.

She told ''I remember thinking to myself, 'Lord, please don't let this boat capsize. Please let us get to shore in one safe, sound piece. I just want to see tomorrow.

''[There was] no more shore, no more land, we're seeing no more of the buoys, no more of the boats passing by - it's just in the middle of nowhere, so we realized that we're lost.''

The gang tried to call for help on their mobile phones, but they were so far from shore no one had any signal - except for Kelly.

She explained: ''I was like, 'Please, Lord, give me two bars'. He gave me two bars and we contacted some folks that were on land and they helped us.''

A towboat was finally sent to rescue them, and they arrived back in Provincetown over 10 hours after they first realised they were lost.

Kelly said: ''The waves coming in were like 5 to 10 feet high and the boat was only a 27-foot boat and it felt like forever to get back to shore.''

The Destiny's Child star is adamant she won't to get on another boat ''for a long time - a very long time.''
