Justin Timberlake and wife Jessica Biel wore complementing outfits to the Las Vegas premiere of the film "Runner, Runner."

The couple took to the red carpet at the Planet Hollywood Resort & Casino in Las Vegas in support of the movie, a high-stakes online poker drama which Timberlake has a starring role in alongside Ben Affleck and Gemma Arterton, who were also at the premiere.

Timberlake and Biel both wore suits on the red carpet, matching their outfits in a notable first for the couple. Timberlake wore a dapper navy blue suit with black lapel detailing and casually wore his jacket open with no tie.

Biel's suit was a step out of her typical style flair -- she rocked a double-breasted Dolce & Gabbana suit from the design house's Resort 2014 collection. The tailored suit featured satin shawl-collar lapels and diamond-encrusted buttons, which Biel styled with an ivory button-up blouse and black pointed-toe heels. She completed the look with a neutral makeup, sapphire earrings, oxblood-painted nails and a Mark Cross "Grace" box bag.

Timberlake and Biel will celebrate their first anniversary as a married couple this October, after tying the knot in an Italian ceremony Oct. 19, 2012. The two dated on-and-off beginning in 2007 before Timberlake proposed to the actress in 2011.

In addition to the film, Timberlake is busy promoting part 2 of his highly successful musical comeback album, "The 20/20 Experience," due out Sept. 30. The "Suit & Tie" singer posted a teaser from a new song off the album on his official Instagram page on Sept. 19.

"Runner, Runner" hits theaters Oct. 4.
