Kate Hudson and Matthew Bellamy always make time for romance!

At the premiere of The Reluctant Fundamentalist, which also served as the opening ceremony for the Venice Film Festival August 29, the actress, 33, and her musician fiance, 34, snuck in a quick kiss before walking the red carpet together.

After posing for joint photos, the Muse frontman's future wife took a few solo shots. Thirteen months after giving birth to her second child, Hudson looked slim and sensational in a curve-hugging, Swarovski crystal-embellished Atelier Versace gown, which she paired with an Edie Parker clutch and Faberge jewelry.

Earlier that day, Hudson joined costar Liev Schreiber, 44, for a photo call to promote the film, which is expected to hit theaters in 2013.

Engaged since April 2011, Hudson and Bellamy welcomed a son, Bingham, in July 2011. Hudson is also mom to son Ryder, 8, with ex-husband and Black Crowes musician Chris Robinson, 45. In April, Hudson's actress mom, Goldie Hawn, 66, told Us Weekly the Something Borrowed star isn't "prepping for a wedding" anytime soon. "She's very happy. She's a great mom, the baby's beautiful, and they'll get married when they're ready," Hawn explained. (At the time, the Private Benjamin actress had been misquoted by another outlet as saying Hudson and Bellamy had already tied the knot.)

In the meantime, Hudson has a film to promote -- not to mention her upcoming guest arc on season 4 of Glee. In her six-episode stint, Hudson plays New York Academy of the Dramatic Arts dance teacher Cassandra July. Her character's vivacity intimidates former high school standout Rachel Berry (Lea Michele, 26).

"I really think having Sarah Jessica Parker and Kate Hudson come in for our fourth season is so exciting," Michele has said of the series' newest guest stars. "I think I'm more excited for this season than ever before."

Glee premieres September 13 at 9 p.m. (EST) on FOX. Previous Glee guest stars include Gwyneth Paltrow, John Stamos, Britney Spears, Neil Patrick Harris and Lindsay Lohan.
