The Witches of East End actress opted for a springtime vibe in her pretty lemon yellow dress, which was designed by Carolina Herrera.
Jenna's gorgeous pastel gown boasted a strapless design and featured ruffle detailing on the front, plus a long, flowing train which draped the ground as she made her way into the event.
The actress - who is mum to daughter Everly, one - toted all her evening essentials in a perspex boxy clutch bag while accessorising with a statement cocktail ring... and her mega-watt engagement and wedding rings, of course!
Jenna tucked her tousled bob hairdo behind one ear to reveal a dazzling ear cuff, before finishing her look with super-sized false lashes, a hint of a rosy gleam on her cheeks and a swipe of natural coloured lipstick on her pout.
The brunette beauty was joined at the ceremony by her husband, Magic Mike actor Channing Tatum, who she met back in 2006 while filming dance movie Step Up.
Channing has been busy promoting his new movie Foxcatcher, in which he stars alongside Steve Carell and Mark Ruffalo. The film tells the true story of wrestling champions Mark and David Schultz as they join a team led by multimillionaire John E. du Pont while training for the Olympic games.
