Sam Smith debuts new boyfriend in vacation photos

British pop sensation Sam Smith has gone public with his budding romance with model Jonathan Zeizel after sharing images of the couple's vacation Down Under.

The Stay With Me hitmaker revealed last month (Dec14) that he had started dating one of the extras from his latest video shoot for Like I Can, but admitted the relationship was in its "very early days".

He added, "I haven't even confirmed with him that we're officially seeing each other."

However, it appears the pair is now officially an item after Smith debuted his new love on Instagram.com while on holiday in Australia.

The singer has uploaded a number of photos from his travels, including a ride on a boat, on which he and Zeizel reenacted a famous scene between Leonardo DiCaprio and Kate Winslet from classic disaster movie Titanic.

The image features Smith taking the actress' place at the edge of the boat, and in the accompanying caption, he quotes the Titanic star's lines by writing, "I'm flying Jack, I'm flying".
