The couple - who met on the set of dance movie Step Up in 2006 - looked loved-up while posing arm-in-arm, with Jenna supporting Channing at the screening of his new flick.
But gorgeous Jenna did steal the limelight from her actor hubby, sporting a knockout satsuma orange dress designed by Cushnie Et Ochs.
Her stunning frock featured sheer mesh cut-out details across the midriff to showcase her taut tum, along with a sexy halterneck design and a floor-skimming hem.
She let her designer gown do all the talking by ditching the jewellery, styling her long bob in tousled waves for a voluminous, beachy look.
The starlet amped up the drama with her make-up too, making her green eyes pop with warm brown shadow teamed with super-sized false lashes, topped with a sweep of peach on her cheeks and apricot lipgloss.
Of course hubby Channing looked pretty fab himself too, sporting a navy striped suit and a matching tie along with a crisp white shirt and polished brogues.
The pair are parents to one-year-old daughter Everly but took a well-earned break from parenting duty to attend the event together.
Channing stars as Caine in Jupiter Ascending, the love interest of Jupiter Jones, played by Mila Kunis. The film also stars The Theory of Everything's Eddie Redmayne and The Riot Club's Douglas Booth.
Meanwhile, Channing's recent film Foxcatcher - which tells the true story of wrestling champions Mark and David Schultz - has received six nominations at this year's Academy Awards, taking place on 22 February.
