Just call her Mrs. SexyBack -- but the side and front aren't too bad, either.

Jessica Biel graced the red carpet again -- her second since marrying and honeymooning with Justin Timberlake last month -- for the Tuesday Nov. 20 L.A. premiere of Hitchcock. Clad in a daring, backless gown by Gucci, the Total Recall actress, 30, showed off a considerable amount of "sideboob" -- i.e. cleavage as seen from the side -- as she posed for photographers, with her hair swept up dramatically.

The dramatic gown also showed off the Seventh Heaven alum's flawless, slim back. She changed into a white minidress for the film's afterparty.

It's a major switch-up from Biel's look just two days earlier at the NYC premiere of the film, in which she wore a sheer, silver bead and lamé mousseline embroidered tunic and pant by Oscar de la Renta. The stunning star drew mixed reactions for that chosen ensemble: Out of nearly 12,000 votes, 51 percent of Us Weekly readers online hated the Golden Girls-esque look, with 49 percent approving of the de la Renta outfit.

In Hitchcock, the newlywed actress stars as real-life actress Vera Miles alongside Anthony Hopkins, Helen Mirren and Scarlett Johansson in a look at the making of director Alfred Hitchcock's 1961 horror masterpiece Psycho.

There's one A-lister Biel is still dying to work with: Her husband!

"I absolutely adore him. I actually would prefer him to direct me in something," she said of Timberlake, 31. "I think that would be the way to go."
