Julia Roberts is "obsessed" with her husband Daniel Moder and lets him choose her clothes.

The 47-year-old actress has been married to Moder - with whom she has twins Phinneaus and Hazel, 11, and son Henry, eight - for 13 years but they are just as much in love as ever.

Asked if there is anything she is obsessed with at the moment at the Hammer Museum's 13th Annual Gala in the Garden here, Roberts pointed at her spouse and said: "He's right there," reports people.com.

The "Pretty Woman" actress donned a dress and blazer for the event, which honoured Diane Keaton and revealed she had let her husband select her outfit for the evening.

"It's Bottega Veneta, and my husband picked it," she said.

Meanwhile, Moder admitted he had been debating between the outfit his wife walked the red carpet in and another ensemble, but decided the dress "was better".

"I think, absolutely, hit it right on the nose. Nice colour, nice shape. She wears it well," he added.
