While Australian stars shone on the red carpet at the Oscars, "eyebrow artist" Sharon-Lee Hamilton was hard at work behind-the-scenes.

Hamilton, who has previously tended to Princess Mary and George Clooney, wouldn't be drawn on her flying visit to the United States, but did confirm she looked after four A-listers for a brow wax and trim.

It was rumoured they included Leonardo DiCaprio and his best mate, Tobey Maguire.

Hamilton was first introduced to the Titanic star through Maguire's ex-wife, Jennifer Meyer.
