The superstar has been enjoying a summer vacation cruising around Europe with Australian entertainment mogul Packer, but a lunch date on Wednesday got off to a rocky start after Carey lost her footing as she descended the steps of the cruiser to climb into a waiting speedboat.

The singer tripped in her chunky heels, and narrowly avoided injury as one of Packer's staff members promptly offered his arm to help Carey regain her balance.

The Hero hitmaker went public with her romance with Packer last month (Jun15), when they were photographed together in Capri, Italy.
